Surah Al-Hijr — Ayah 66 (15:66)
وَقَضَيۡنَآ إِلَيۡهِ ذَٰلِكَ ٱلۡأَمۡرَ أَنَّ دَابِرَ هَٰٓؤُلَآءِ مَقۡطُوعٞ مُّصۡبِحِينَ ٦٦
English translation (Saheeh International)
And We conveyed to him [the decree] of that matter: that those [sinners] would be eliminated by early morning.
Brief commentary
We made known to Lot by means of revelation the matter that We had decreed, which was that those people will be annihilated by the last of them being destroyed when morning comes.
