وَقَالَ ٱلَّذِينَ ٱتَّبَعُوا۟ لَوْ أَنَّ لَنَا كَرَّةًۭ فَنَتَبَرَّأَ مِنْهُمْ كَمَا تَبَرَّءُوا۟ مِنَّا ۗ كَذَٰلِكَ يُرِيهِمُ ٱللَّهُ أَعْمَٰلَهُمْ حَسَرَٰتٍ عَلَيْهِمْ ۖ وَمَا هُم بِخَٰرِجِينَ مِنَ ٱلنَّارِ
And those who were but followers will say: If a return were possible for us, we would disown them even as they have disowned us. Thus will Allah show them their own deeds as anguish for them, and they will not emerge from the Fire.
Surah Al-Baqara(2:167)
