Insights and Lessons from Imam Ar-Razi’s Mafatih al-Ghayb on Al-Isra Verses 4–6

This is Imam Fakhr ad-Din Ar-Razi on verses 4–6 of Surah Al-Isra:

﴾وَقَضَيۡنَاۤ إِلَىٰ بَنِیۤ إِسۡرَ ٰⁿءِیلَ فِی ٱلۡكِتَـٰبِ لَتُفۡسِدُنَّ فِی ٱلۡأَرۡضِ مَرَّتَيۡنِ وَلَتَعۡلُنَّ عُلُوࣰّا كَبِيرࣰا ۝ فَإِذَا جَاۤءَ وَعۡدُ أُولَىٰهُمَا بَعَثۡنَا عَلَيۡكُمۡ عِبَادࣰا لَّنَاۤ أُو۟لِی بَأۡسࣲ شَدِيدࣲ فَجَاسُوا۟ خِلَـٰلَ ٱلدِّيَارِۚ وَكَانَ وَعۡدࣰا مَّفۡعُولࣰا ۝ ثُمَّ رَدَدۡنَا لَكُمُ ٱلۡكَرَّةَ عَلَيۡهِمۡ وَأَمۡدَدۡنَـٰكُم بِأَمۡوَ ٰلࣲ وَبَنِينَ وَجَعَلۡنَـٰكُمۡ أَكۡثَرَ نَفِيرًا ۝﴿

“And We made known to the Children of Israel in the Scripture: ‘You will surely cause corruption on the earth twice, and you will surely commit great arrogance.’ So when the promise of the first of them came, We sent against you servants of Ours of great might, and they probed through the homes — and it was a fulfilled promise. Then We gave you the return [of victory] over them and supplied you with wealth and children and made you more numerous in fighting men.”

1. The Structural Connection — Why These Verses Follow Verses 2–3

Ar-Razi opens with structural insight:

“Know that when Allah Most High mentioned His blessing upon the Children of Israel by sending down the Torah upon them and making the Torah a guidance for them — He clarified that they were not guided by its guidance but rather fell into corruption. So He said: ‘And We made known to the Children of Israel in the Scripture: You will surely cause corruption on the earth twice.'”

This is Ar-Razi’s signature structural framing. Verses 2–3 set up: “We gave them the Torah, We made it guidance.” Then verses 4–5 reveal the tragic outcome: “They were not guided. They corrupted.” The verses form a single argument about the relationship between divine guidance and human response.

KEY LESSONS:

• Guidance does not guarantee being guided. Bani Isra’il had the Torah, the prophets, the law — and they still corrupted. Possessing the Book is not the same as following it. The same warning applies to every community: do not assume that possessing the Qur’an means you are guided by it. The Qur’an is a means; guidance happens when you act upon it.

• Ar-Razi reads the verses in sequence as a logical argument. This is among the great gifts of his tafsir: he doesn’t just explain each verse — he shows you how the verses relate to each other. Read the Qur’an this way: as a sustained argument, where each verse builds upon the previous. Do not isolate verses; trace the thread.

2. Qada’ — The Linguistic Foundation

Ar-Razi establishes the meaning of qada’:

“Al-qada’ in the language is an expression for cutting things off with completion (qat’ al-ashya’ ‘an ihkam).

From it is His saying: ‘And He completed them as seven heavens’ (Fussilat 41:12).

And the poet’s verse:

‘And upon them are two coats of mail — Dawud completed them with skill…’“***

The root meaning of qada’ is cutting off with mastery — like finishing a craftsman’s work. When Allah qada the heavens, He brought them to a completed, perfected state. When He qada a prophecy to Bani Isra’il, He brought the matter to its definitive expression.

“His saying qadayna means: We informed them, gave them news, and revealed to them. The word ila is a connector for al-iha’ (revelation), because the meaning of qadayna is We revealed to them such-and-such.”

So Ar-Razi grounds the preposition-shift (qada’ + ila) in the same insight you saw in Al-Alusi and Ibn Ashur: qada’ here contains the meaning of wahy (revelation), and the preposition ila points to the recipient of the revelation.

KEY LESSONS:

• The root meaning of qada’ is completion with mastery. Allah’s decree is not arbitrary — it is the finishing of a matter with the precision of a master craftsman. When Allah decrees something, it is brought to its perfect completion — like Dawud’s coats of mail, which were perfectly crafted. Trust Allah’s decrees as you would trust the work of a master craftsman: every detail is intentional, and the finished product is precisely what was intended.

• The cross-reference to Fussilat 41:12 — “And He completed (fa-qadahunna) them as seven heavens” — shows the same verb being used for the creation of the cosmos. Both creating the heavens and warning Bani Isra’il are acts of qada’ — bringing matters to their finished state. Your life, too, is being brought to its qada’. Allah is finishing the matter of you. Every event in your life is part of the master craftsman’s perfecting of his work.

3. Fi-l-Ard — Ar-Razi’s Unique Identification

Ar-Razi takes a distinctive position on which land:

“His saying ‘in the earth’ — means: the land of Egypt.”

This is unusual. Most commentators read al-ard as referring either to the earth in general or to the land of Sham/Jerusalem. Ar-Razi alone among the major commentators reads it as the land of Egypt — connecting the corruption to the historical territory where Bani Isra’il lived under Musa عليه السلام and from which they were freed.

On this reading, the corruption is connected to the very land where Allah’s miracles for Bani Isra’il occurred — making it doubly grievous.

KEY LESSON: Be careful about corrupting in the very places where Allah has shown you mercy. If Ar-Razi’s reading is correct, Bani Isra’il’s corruption was committed in Egypt itself — the land where Allah split the sea for them, drowned Pharaoh for their sake, and gave them mann and salwa. The deepest ingratitude is corrupting in the very place of your rescue. Examine the spaces in your own life where Allah has been most merciful — and ensure you are not corrupting there.

4. ‘Uluwwan Kabira — Tyranny Defined

Ar-Razi’s gloss:

“His saying ‘and you will surely elevate in great elevation’ means: that your elevation over people without right will be a great elevation — because it is said of every tyrant: he has elevated and become great.”

So ‘uluw kabir = systematic tyranny against people without right. The metaphor of “elevation” captures unjustly placing yourself above others.

KEY LESSON: Tyranny is described in Arabic as elevation. Every tyrant is described as one who has risen up unjustly. Examine your own elevations: if you have risen above others with right (through legitimate work, divinely-granted talent, lawful position), that is acceptable. But if you have risen above others without right — through oppression, manipulation, or domination — that is ‘uluw in the Qur’anic sense. Real status before Allah is based on taqwa, not on artificial elevation.

5. The Three Major Historical Interpretations

Ar-Razi surveys the three views on who the “servants of great might” were:

View 1: Bukhtnassar (Nebuchadnezzar)

“It is said: Bani Isra’il became great and arrogant, made permissible the forbidden, killed the prophets, and shed blood — and this was the first of the two corruptions.

So Allah gave power over them to Bukhtnassar, who killed forty thousand of them — from those who recited the Torah — and took the remainder to the land of his own [Babylon]. They remained there in humiliation until Allah enabled another king who attacked the people of Babylon.

It happened that he married a woman from Bani Isra’il, and that woman asked the king to return the Children of Israel to Bayt al-Maqdis — and he did so. After a period, prophets arose among them, and they returned to the best of what they were. This is His saying: ‘Then We gave you the return [of victory] over them.'”

This is a uniquely tender narrative detail that Ar-Razi preserves: the return of Bani Isra’il from Babylonian captivity was secured through the intercession of a Jewish woman married to a foreign king. This may be a reference to the biblical figure of Esther (Hadassah), who, according to the biblical book of Esther, was a Jewish woman married to the Persian king Ahasuerus and successfully interceded for her people.

View 2: Jalut (Goliath)

“The intention in His saying ‘We sent against you servants of Ours’ is that Allah Most High gave power over them to Jalut until he destroyed them and annihilated them.

And His saying ‘Then We gave you the return’ is that Allah strengthened Talut until he fought Jalut, and gave victory to Dawud until he killed Jalut. That is the return of victory.”

View 3: The Magians (Zoroastrians)

“His saying ‘We sent against you servants of Ours’ is that Allah Most High cast terror of Bani Isra’il into the hearts of the Magians. Then when sins increased among [Bani Isra’il], He removed that terror from the hearts of the Magians — so they pursued them, intensified in killing them, annihilating them, and destroying them.”

KEY LESSONS:

• The intercession of a single righteous woman saved an entire people. On the Bukhtnassar narrative, the return of Bani Isra’il to Jerusalem came through a Jewish woman who became the queen of a foreign king and used her position to intercede for her people. Never underestimate the power of a single soul in a strategic position. Allah’s plans of mercy unfold through people we might overlook. Be ready, in whatever position Allah has placed you, to intercede for those in need.

• Terror in the hearts of enemies is among Allah’s protections — and its removal is among His punishments. On the third view, Bani Isra’il had been protected by Allah casting fear of them into the hearts of the Magians. When they corrupted, Allah simply removed that fear — and the Magians, no longer restrained by fear, attacked. You may be being protected from many enemies by fear of you in their hearts that Allah Himself placed there — fear you did not earn but that protects you. Earn that protection by your righteousness; if you do not, Allah may simply remove it, and you will be exposed. The Prophet ﷺ said in a sound hadith: “I have been given victory by terror cast in the hearts of my enemies — at a distance of one month’s journey.” (Bukhari and Muslim) The principle applies: divine terror is a real protection.

6. Ar-Razi’s Methodological Statement — On Identifying the Specific Invaders

Ar-Razi’s striking methodological observation:

“Know that there is no great purpose attached to knowing those peoples by their specific identities. Rather, the intended meaning is that — when they multiplied in sins — Allah gave power over them to peoples who killed them and destroyed them.”

This is one of the most refreshing methodological statements in classical tafsir. Ar-Razi acknowledges that the specific historical identification (Bukhtnassar vs. Jalut vs. the Magians) is not the main point of the verse. The main point is the theological pattern: when corruption increases, divine punishment through worldly agents follows.

KEY LESSONS:

• Don’t get lost in historical minutiae at the expense of theological meaning. Ar-Razi reminds us that which specific king attacked Bani Isra’il is far less important than why it happened and what it means for us. Read the Qur’an for its moral and theological message, not primarily as a history book. The historical details are context; the principles are the lesson.

• The pattern is more important than the personalities. Multiplied sins → divine permission for foreign enemies → destruction. This pattern is universal — it does not matter whether the agent is Bukhtnassar or Jalut or the Magians or some 21st-century military power. The pattern repeats wherever the conditions are met. Apply this lesson to your own community’s situation: if you see foreign powers achieving dominance over your community, ask first what internal corruptions may have invited Allah’s permission for that.

• Ar-Razi’s restraint is itself a teaching method. He doesn’t pick one historical interpretation and declare the others wrong. He presents all three, then says: the specific identification doesn’t matter. This is intellectual humility combined with theological clarity — and it is a model for engaging contested historical questions in religious texts. Focus on what is clear and morally instructive; leave aside what is contested and historically peripheral.

7. Fa-Jasu — The Multiple Glosses

Ar-Razi surveys the linguistic shades of fa-jasu:

*“Al-Layth said: al-jaws and al-jawasan — the going back and forth through the homes and houses in corruption.

Various interpretations:

— From Ibn ‘Abbas: they searched (fattashu).

— From Abu ‘Ubaydah: they sought out those who were in them.

— From Ibn Qutaybah: **they wreaked havoc and caused corruption (‘athu wa afsadu).

— From Az-Zajjaj: they circulated through the homes [seeing] whether anyone remained whom they had not killed.

Al-Wahidi: Al-jaws is moving back and forth and searching — and that is consistent with all of what they said.”

So fa-jasu combines:

1. Searching (Ibn ‘Abbas)
2. Hunting down survivors (Abu ‘Ubaydah, Az-Zajjaj)
3. Wreaking destruction (Ibn Qutaybah)
4. Moving back and forth through homes in corruption (Al-Layth)

KEY LESSON: The verb jasa compresses the complete horror of military invasion at the household level — searching, hunting, destroying, moving systematically through every interior space. This is what the Babylonian invasion of Jerusalem looked like on the ground: soldiers in every home, methodically. No description in any later war literature captures the experience more precisely than this single Arabic verb. When the Qur’an chooses one word over many possible synonyms, it is because that single word carries the maximum compression of meaning.

8. Wa Kana Wa’dan Maf’ula — The Inescapable Decree

Ar-Razi’s powerful statement:

“His saying ‘And it was a fulfilled promise’ means: Allah’s decree of that was a definitive, decisive decree — admitting no annulment (naqd) and no abrogation (naskh).”

Ar-Razi uses two technical legal terms here:

• Naqd — the legal annulment of a ruling
• Naskh — the legal abrogation of one ruling by another

The decree of punishment, Ar-Razi says, was neither annullable nor abrogatable. Once issued and once its conditions were met, it was executed.

KEY LESSON: Some divine decrees are permanent — beyond the scope of even Allah’s normal practice of abrogation. This is theologically significant. Allah’s commands can sometimes be abrogated (this is the Qur’anic doctrine of naskh), but certain prophecies and certain punishments, once decreed and once their conditions are met, are absolute. The promise of punishment for corruption, once the corruption occurs, is not negotiable. The window for changing the outcome is before you fulfill the conditions of the punishment — not after.

9. Thumma Radadna Lakumu-l-Karrata — The Return

Ar-Razi’s gloss:

“His saying ‘Then We gave you the return [of victory]’ means: We destroyed your enemies and returned the dominion (ad-dawlah) and the strength to you, and ‘made you more numerous in fighting men’.

An-nafir — the count of men. Its origin is from one who marches out with a man from his clan and his people. An-nafir and an-nafir are equivalent — like al-qadir and al-qadir.

We have mentioned the meaning of nafar at His saying: ‘Why should not a contingent from every group march forth (nafara)?’ (At-Tawbah 9:122), and His saying: ‘March forth (infaru) light or heavy’ (At-Tawbah 9:41).”

Ar-Razi explicitly cross-references the two verses in Surah At-Tawbah where the same root nafara is used — connecting the nafir of restoration here with the Qur’anic call to military mobilization for the believers.

KEY LESSONS:

• The same root that describes Bani Isra’il’s restoration in fighting capacity is used to describe the Muslim ummah’s call to military mobilization in Surah At-Tawbah. This is significant: military capacity is a blessing from Allah and is part of being a flourishing community. Don’t apologize for a community’s military strength when it is in the service of righteousness. The believers, like restored Bani Isra’il, are commanded to be ready to march.

• The pattern of restoration includes the return of dominion (ad-dawlah). Ad-dawlah in Arabic carries the meaning of political turn, sovereign rule, state authority. Allah’s restoration of His people includes restoring their political autonomy — not just spiritual flourishing. Pray for your ummah’s restoration to include both spiritual revival and political dignity.

10. Ar-Razi’s Theological Defense of Qadar — Three Arguments from This Verse

This is the centerpiece of Ar-Razi’s commentary — his three-fold argument that these verses prove the Sunni doctrine of divine decree against the Mu’tazila.

Argument 1: The Prophecy Itself Proves Determinism

**“Allah Most High said: ‘And We made known to the Children of Israel in the Scripture: You will surely cause corruption on the earth twice and you will surely commit great arrogance.’ And this qada’ — at the lowest of its possible meanings — is a definitive ruling and a final report.

So it is established that Allah Most High gave news about them — that they would imminently embark on corruption and sins — as a definitive report that does not admit abrogation — because qada’ means definitive ruling, as we have explained.

Then Allah Most High emphasized that qada’ with additional emphasis, saying: ‘And it was a fulfilled promise.'”

So the strongest emphasis in Arabic — qadayna + lam + nun + wa’dan maf’ula — establishes that the prophecy is absolutely fixed. Then Ar-Razi delivers the killing blow:

**“When this is established, we say: the non-occurrence of that corruption from them would entail:

— The transformation of Allah’s truthful news into a lie,

— The transformation of His definitive ruling into invalidity,

— The transformation of His true knowledge into ignorance.

**And all of that is impossible. So the non-occurrence of their embarking on that corruption was impossible. Therefore their embarking on it was necessarily required and inescapable — admitting no abrogation or removal — even though they were commanded to abandon it and cursed for committing it.

And this proves our position: that Allah may command something and prevent it [from being done], and may forbid something and decree its occurrence.”

This is a powerful syllogism. If Allah’s prophecy that they would corrupt could fail to come true, then either:

1. Allah’s report was a lie (impossible)
2. Allah’s ruling was invalid (impossible)
3. Allah’s knowledge was actually ignorance (impossible)

Therefore the prophecy had to come true — which means Bani Isra’il’s corruption was necessitated by Allah’s prior decree, even though they were morally responsible and condemned for it.

KEY LESSONS:

• Prophecy is itself proof of determinism. Ar-Razi’s argument is one of the most elegant in classical Islamic theology: every fulfilled prophecy proves that what was prophesied had to happen, and therefore proves the doctrine of qadar. You cannot believe in prophecy and deny qadar. They are logically connected.

• The Sunni paradox: Allah commands what He has decreed against, and forbids what He has decreed to occur. This is the heart of Ash’ari Sunni theology. Allah’s command and Allah’s decree are two separate things. He commanded Bani Isra’il not to corrupt — yet His decree was that they would corrupt. Both are true. Live as though only the command exists (i.e., obey Allah’s commands and avoid His prohibitions), while recognizing that Allah’s knowledge encompasses what you will do. The command is your responsibility; the decree is Allah’s prerogative.

• Don’t try to escape responsibility by appealing to qadar. Bani Isra’il were cursed for their corruption — even though it was decreed. The decree does not eliminate moral responsibility. Iblis tried this argument: “My Lord, because You misled me…” (Al-Hijr 15:39). Allah did not accept it as an excuse. Neither should you.

Argument 2: The Attribution of Ba’th to Allah

“His saying ‘We sent against you servants of Ours of great might’ — and the intended meaning is those who were given dominion over Bani Isra’il through killing, plundering, and capture. Allah Most High clarified that He is the one who sent them against Bani Isra’il.

And there is no doubt that the killing of Bani Isra’il, the plundering of their wealth, and the capture of their children was full of great injustice and severe sins. Then Allah attributed all of that to Himself by His saying ‘We sent against you’.

And this proves that good and evil, obedience and disobedience, are all from Allah Most High.”

This is the foundational Ash’ari position: Allah is the Creator of all events, including the evil acts of His servants — without thereby being morally responsible for them. The doer of evil is responsible; the Creator is not.

Al-Jubba’i’s Mu’tazili Response — And Ar-Razi’s Refutation

Ar-Razi then explicitly engages Al-Jubba’i (a leading Mu’tazili theologian) who tried to escape this argument:

“Al-Jubba’i answered this in two ways:

The first: that the meaning of ‘We sent against you’ is that Allah Most High commanded those peoples to invade Bani Isra’il because of the corruption that appeared among them. So that act was attributed to Allah from the angle of command.

The second: that the intended meaning is We left them alone with Bani Isra’il and did not cast fear of Bani Isra’il into their hearts. The summary: the intended meaning of this ba’th (sending) is al-takhliyah (leaving alone) and ‘adam al-man’ (non-prevention).”

Ar-Razi’s refutation of both Mu’tazili answers:

**“Know that the first answer is weak — because those who intended to destroy Bayt al-Maqdis, burn the Torah, and kill those who memorized the Torah — it is not permissible to say that they did that by Allah’s command.

**The second answer is also weak — because al-ba’th (sending) for an action is an expression of strengthening for it and casting strong motivations into the heart, whereas al-takhliyah (leaving alone) is an expression of non-prevention. The first is a positive act; the second is an omission. So interpreting al-ba’th as al-takhliyah is interpreting one of two opposites by the other — and that is not permissible.

So what we have mentioned is established as correct. And Allah knows best.”

This is a masterful refutation. Ar-Razi makes two devastating points:

1. Against Al-Jubba’i’s first interpretation: It would mean that Allah commanded the burning of the Torah and the killing of the prophets’ memorizers. This is theologically untenable — Allah did not command those acts; the disbelievers chose them.

2. Against Al-Jubba’i’s second interpretation: Ba’th (sending) and takhliyah (leaving alone) are linguistic opposites. Ba’th means positive causation — strengthening someone to do something, casting motivations into their heart. Takhliyah means negative omission — simply not preventing something. To interpret ba’th as takhliyah is to interpret a word as its own opposite — which is linguistically impossible.

KEY LESSONS:

• The Sunni position takes the Qur’an’s plain language seriously. When Allah says “We sent against you” (ba’athna ‘alaykum), the plain meaning is that Allah actively brought about the invasion. The Mu’tazili attempt to interpret ba’th as takhliyah (mere non-prevention) violates the language itself. Don’t reinterpret divine speech to fit a theological framework. Let the language speak; adjust the framework if it conflicts.

• Mu’tazili theology forces linguistic violence. Ar-Razi’s critique is that the Mu’tazila were so committed to their theological framework that they had to reinterpret words as their opposites to make the Qur’an fit. This is a red flag in any interpretive system: if you have to read words as meaning their opposite, your framework is broken.

• Allah is the Creator; the actor is the responsible doer. The Sunni resolution is: Allah is the Creator of the act of invasion (so He really did “send” them), AND the disbelievers are responsible for choosing to invade with cruel intentions. Both truths coexist without either negating the other. This is the deep mystery of qadar: divine sovereignty and human responsibility are both fully real.

The Master Lesson from Ar-Razi on Verses 4–6

Ar-Razi’s treatment delivers the most rigorous Ash’ari Sunni defense of qadar in any classical tafsir on these verses — and lays out the inescapable logical structure of divine sovereignty:

🌙 Allah knew what Bani Isra’il would do. 🌙 Allah informed them of what they would do — as a definitive decree. 🌙 The fulfillment of the decree was therefore necessary — admitting no annulment or abrogation. 🌙 Allah sent the invaders against them — and this sending was a positive act of divine causation, not mere non-prevention. 🌙 The invaders remained responsible for their cruelty. 🌙 Bani Isra’il remained responsible for their corruption — and were cursed for it. 🌙 Both the decree and the responsibility are simultaneously real.

This is the paradox of qadar that defines Sunni Islam: Allah’s sovereignty is total, and human responsibility is total — and the two coexist without contradiction, even though we cannot fully comprehend the mechanism.

The Mu’tazila tried to escape this paradox by making Allah’s sovereignty less than total (denying that He directly creates evil acts) and human responsibility more than total (making humans the sole creators of their actions). Ar-Razi’s argument is that this Mu’tazili move actually violates the language of the Qur’an itself — turning ba’th (sending) into takhliyah (leaving alone), which is reading a word as its own opposite.

Wa qadayna ila Bani Isra’il fi-l-Kitabi latufsidunna fi-l-ardi marratayn wa lata’lunna ‘uluwwan kabira. Fa idha ja’a wa’du ulahuma ba’athna ‘alaykum ‘ibadan lana uli ba’sin shadidin fa-jasu khilala-d-diyar wa kana wa’dan maf’ula. Thumma radadna lakumu-l-karrata ‘alayhim wa amdadnakum bi-amwalin wa banin wa ja’alnakum akthara nafira.

“And We made known to the Children of Israel in the Scripture: ‘You will surely corrupt on the earth twice, and you will surely commit great arrogance.’ So when the promise of the first of them came, We sent against you servants of Ours of great might, and they probed through the homes — and it was a fulfilled promise. Then We gave you the return of victory over them and supplied you with wealth and children and made you more numerous in fighting men.”

Allah’s sovereignty is total — including over the actions of the disbelievers who invade His people in punishment of their corruption. Allah’s commands are also total — including the prohibition of the very corruption He has decreed will occur. The believer holds both truths together: I am commanded to do right and avoid wrong; I am responsible for my choices; and Allah’s knowledge and decree encompass everything. Live by the command. Trust the decree. Do not use the decree as an excuse — Bani Isra’il were cursed for their corruption even though Allah decreed it. The mystery of qadar is not a license for fatalism; it is a humbling recognition of Allah’s sovereignty within which my responsibility remains absolutely real.
