يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ قُوٓاْ أَنفُسَكُمۡ وَأَهۡلِيكُمۡ نَارًا وَقُودُهَا ٱلنَّاسُ وَٱلۡحِجَارَةُ عَلَيۡهَا مَلَٰٓئِكَةٌ غِلَاظٌ شِدَادٌ لَّا يَعۡصُونَ ٱللَّهَ مَآ أَمَرَهُمۡ وَيَفۡعَلُونَ مَا يُؤۡمَرُونَ
O ye who believe! save yourselves and your families from a Fire whose fuel is Men and Stones, over which are (appointed) angels stern (and) severe, who flinch not (from executing) the Commands they receive from Allah, but do (precisely) what they are commanded.<br/>
O you who believe! Guard yourselves and your families, by enjoining obedience to God, against a Fire whose fuel is, disbelieving, people and stones, such as those idols of theirs made of that [stone] - the meaning is that it is extremely hot, fuelled by the above-mentioned, unlike the fire of this world which is fuelled by wood and the like - over which stand angels, its keepers - numbering nineteen as will be stated in [soorat] al-Muddaththir [Q. 74:30] - stern, a sternness of the heart, mighty, in [their power of] assault, who do not disobey God in what He commands them (maa amarahum is a substitution for His Majesty ['God']), in other words, they do not disobey the command of God, but do what they are commanded - this is [reiterated] for emphasis; the verse is meant as a threat to deter believers from apostatising and for hypocrites who believe only with their tongues and not with their hearts.
