Futility of Late Repentance

كَمْ أَهْلَكْنَا مِن قَبْلِهِم مِّن قَرْنٍ فَنَادَوا۟ وَّلَاتَ حِينَ مَنَاصٍ

How many a generation have We destroyed before them, and they [then] called out; but it was not a time for escape.

فَلَمَّا رَأَوْا۟ بَأْسَنَا قَالُوٓا۟ ءَامَنَّا بِٱللَّهِ وَحْدَهُۥ وَكَفَرْنَا بِمَا كُنَّا بِهِۦ مُشْرِكِينَ

And when they saw Our punishment, they said, "We believe in Allāh alone and disbelieve in that which we used to associate with Him."
