فَإِذَا نُقِرَ فِي النَّاقُورِ
When the Trumpet will be sounded,
فَذَٰلِكَ يَوْمَئِذٍ يَوْمٌ عَسِيرٌ
that will be a day of hardship,
عَلَى الْكَافِرِينَ غَيْرُ يَسِيرٍ
not at all easy for the faithless.
ذَرْنِي وَمَنْ خَلَقْتُ وَحِيدًا
Leave Me [to deal] with him whom I created alone,
وَجَعَلْتُ لَهُ مَالًا مَّمْدُودًا
and furnished him with extensive means,
وَبَنِينَ شُهُودًا
[gave him] sons to be at his side,
وَمَهَّدتُّ لَهُ تَمْهِيدًا
and facilitated [all matters] for him.
ثُمَّ يَطْمَعُ أَنْ أَزِيدَ
Still he is eager that I should give him more.
كَلَّا ۖ إِنَّهُ كَانَ لِآيَاتِنَا عَنِيدًا
No indeed! He is an obstinate opponent of Our signs.
سَأُرْهِقُهُ صَعُودًا
Soon I will overwhelm him with hardship.
إِنَّهُ فَكَّرَ وَقَدَّرَ
Indeed he reflected and decided.
فَقُتِلَ كَيْفَ قَدَّرَ
Perish he, how he decided!
ثُمَّ قُتِلَ كَيْفَ قَدَّرَ
Again, perish he, how he decided!
ثُمَّ نَظَرَ
Then he looked;
ثُمَّ عَبَسَ وَبَسَرَ
then frowned and scowled.
ثُمَّ أَدْبَرَ وَاسْتَكْبَرَ
Then he walked away disdainfully,
فَقَالَ إِنْ هَـٰذَا إِلَّا سِحْرٌ يُؤْثَرُ
saying, ‘It is nothing but traditional sorcery.
إِنْ هَـٰذَا إِلَّا قَوْلُ الْبَشَرِ
It is nothing but the speech of a human.’
سَأُصْلِيهِ سَقَرَ
Soon I will cast him into Saqar.
وَمَا أَدْرَاكَ مَا سَقَرُ
And what will show you what is Saqar?
لَا تُبْقِي وَلَا تَذَرُ
It neither spares, nor leaves [anything].
لَوَّاحَةٌ لِّلْبَشَرِ
It burns the skin.
عَلَيْهَا تِسْعَةَ عَشَرَ
There are nineteen [keepers] over it.
وَمَا جَعَلْنَا أَصْحَابَ النَّارِ إِلَّا مَلَائِكَةً ۙ وَمَا جَعَلْنَا عِدَّتَهُمْ إِلَّا فِتْنَةً لِّلَّذِينَ كَفَرُوا لِيَسْتَيْقِنَ الَّذِينَ أُوتُوا الْكِتَابَ وَيَزْدَادَ الَّذِينَ آمَنُوا إِيمَانًا ۙ وَلَا يَرْتَابَ الَّذِينَ أُوتُوا الْكِتَابَ وَالْمُؤْمِنُونَ ۙ وَلِيَقُولَ الَّذِينَ فِي قُلُوبِهِم مَّرَضٌ وَالْكَافِرُونَ مَاذَا أَرَادَ اللَّهُ بِهَـٰذَا مَثَلًا ۚ كَذَٰلِكَ يُضِلُّ اللَّهُ مَن يَشَاءُ وَيَهْدِي مَن يَشَاءُ ۚ وَمَا يَعْلَمُ جُنُودَ رَبِّكَ إِلَّا هُوَ ۚ وَمَا هِيَ إِلَّا ذِكْرَىٰ لِلْبَشَرِ
We have assigned only angels as keepers of the Fire, and We have made their number merely a stumbling block for the faithless, and so that those who were given the Book may be reassured, and the faithful may increase in [their] faith, and so that those who were given the Book and the faithful may not be in doubt, and so that the faithless and those in whose hearts is a sickness may say, ‘What did Allah mean by this description?’ Thus does Allah lead astray whomever He wishes and guides whomever He wishes. No one knows the hosts of your Lord except Him, and it is just an admonition for all humans.
English translation: Ali Quli Qarai
What the passage says. A trumpet-blast (fa-idhā nuqira fī l-nāqūr) opens "a hard day for the disbelievers." Then God turns to a single adversary — dharnī wa-man khalaqtu waḥīdan, "Leave Me with him whom I created alone" — recounting the wealth, sons and ease given him, his ingratitude and craving for more, and his cold calculation against the Qurʾān ("he reflected and devised… this is only magic transmitted, only the speech of a mortal"). The sentence is Saqar, "the scorcher," "over which are nineteen" (vv. 30–31), whose number is declared "a trial" that confirms the People of the Book, increases the believers' faith, and provokes the diseased of heart to ask "what did God intend by this?"
The occasion (near-unanimous). Al-Mīzān, Majmaʿ al-Bayān, al-Tibyān and al-Qummī agree the man is al-Walīd b. al-Mughīra al-Makhzūmī; web cross-checks confirm a near-unanimous classical consensus that vv. 11–26 describe him and his plot. al-Ṭabarsī preserves the Dār al-Nadwa council (the Quraysh settling on "magician" because magic "separates the loving"), while al-Qummī and al-Mīzān carry the recitation-of-Fuṣṣilat version (al-Walīd shuddering at "a thunderbolt like ʿĀd and Thamūd," then conceding the Qurʾān's "sweetness… it rises and is not risen above," before devising the charge of "magic"). The Imāmī sources add (al-ʿAyyāshī, via al-Ṭabarsī and al-Burhān) the reading that al-Waḥīd connotes "one of no known father."
The lexical and theological core. Ṭabarsī and Ṭūsī supply the dense apparatus — Saqar undeclined for gender and definiteness, lawwāḥa as scorching/blackening the skin, ʿanīd as stubborn enmity — and both, with al-Mīzān, read the nineteen as angel-wardens whose number is a fitna: a test that makes the Torah-and-Gospel agreement a proof of prophethood and exposes Abū Jahl's bravado ("can ten of you not seize one of them?"). al-Mīzān presses two points the others only touch: that "We have not made their number except as a trial" is a making-by-report, not by creation; and that the whole sūra is Meccan, defending this against the claim that "those in whose hearts is disease" requires a Medinan date (hypocrisy, he argues, has Meccan causes too, citing 29:10–11). On "none knows the hosts of your Lord but He," al-Mīzān notes the negation attaches to the hosts themselves, reserving to God all knowledge of their reality and number.
The Imāmī reading (al-Qummī, al-Burhān). Tafsīr al-Qummī and al-Burhān layer a sustained political and eschatological taʾwīl, transmitted as-attributed: nuqira fī l-nāqūr as the veiled Imām/Qāʾim whom God "strikes a point in his heart" to bring forth (al-Mufaḍḍal ← al-Ṣādiq), and the Nāqūr as Gabriel's heavenly proclamation of the walāya; and the whole al-Walīd portrait re-read of "Zufar" — "obstinate to Our signs" = denying ʿAlī's walāya, ṣaʿūd = a torment of the Qāʾim, "this is only magic" = "the Prophet bewitched people through ʿAlī." al-Burhān's long [31–56] run (from al-Kāẓim and others) fixes "those given certainty," "the increase in faith," and "it is but a reminder" all upon the walāya, and the nineteen as its sign. These readings are recorded here as the sources transmit them, not as established meaning.
Convergence and divergence. All six converge on the plain drama: a blessed ingrate who weighed the Qurʾān, branded it magic, and earned Saqar guarded by nineteen whose number tries the deniers. They diverge in register — the two Arabic tafsīrs and al-Mīzān keep the historical-theological frame (al-Walīd, the wardens as a probative fitna), while al-Qummī and al-Burhān recast the same verses through the walāya and the Qāʾim. No source is silent on this passage.
