Yusuf Ayah 110

حَتَّىٰٓ إِذَا ٱسْتَيْــَٔسَ ٱلرُّسُلُ وَظَنُّوٓاْ أَنَّهُمْ قَدْ كُذِبُواْ جَآءَهُمْ نَصْرُنَا فَنُجِّىَ مَن نَّشَآءُ‌ۖ وَلَا يُرَدُّ بَأْسُنَا عَنِ ٱلْقَوْمِ ٱلْمُجْرِمِينَ ١١٠ And when the messengers despaired and their people thought the messengers had been denied help, Our help came to them ?at last?. We then saved whoever We willed, and Our punishment is never averted from the wicked people.
