حَتَّىٰٓ إِذَا ٱسْتَيْـَٔسَ ٱلرُّسُلُ وَظَنُّوٓا۟ أَنَّهُمْ قَدْ كُذِبُوا۟ جَآءَهُمْ نَصْرُنَا فَنُجِّىَ مَن نَّشَآءُ ۖ وَلَا يُرَدُّ بَأْسُنَا عَنِ ٱلْقَوْمِ ٱلْمُجْرِمِينَ
Till, when the messengers despaired and thought that they were denied, then came unto them Our help, and whom We would was saved. And Our wrath cannot be warded from the guilty.
