وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِن وَلِىٍّۢ مِّنۢ بَعْدِهِۦ ۗ وَتَرَى ٱلظَّٰلِمِينَ لَمَّا رَأَوُا۟ ٱلْعَذَابَ يَقُولُونَ هَلْ إِلَىٰ مَرَدٍّۢ مِّن سَبِيلٍۢ
He whom Allah sendeth astray, for him there is no protecting friend after Him. And thou (Muhammad) wilt see the evil-doers when they see the doom, (how) they say: Is there any way of return?
Surah Ash-Shura(42:44)
