كَمْ اَهْلَكْنَا مِنْ قَبْلِهِمْ مِّنْ قَرْنٍ فَنَادَوْا وَّلَاتَ حِيْنَ مَنَاصٍ ( ص: ٣ )
Kam ahlaknaa min qablihim min qarnin fanaadaw wa laata heena manaas (Ṣād 38:3)
How many a generation have We destroyed before them, and they [then] called out; but it was not a time for escape. (Sad  : 3)
1 Mufti Taqi Usmani
How many a generation have We destroyed before them, so they cried out (for mercy), while no time was left for having any refuge.
