35 : 8
أَفَمَن زُيِّنَ لَهُۥ سُوٓءُ عَمَلِهِۦ فَرَءَاهُ حَسَنٗاۖ فَإِنَّ ٱللَّهَ يُضِلُّ مَن يَشَآءُ وَيَهۡدِي مَن يَشَآءُۖ فَلَا تَذۡهَبۡ نَفۡسُكَ عَلَيۡهِمۡ حَسَرَٰتٍۚ إِنَّ ٱللَّهَ عَلِيمُۢ بِمَا يَصۡنَعُونَ
Is one whose evil deed is made appealing to him so he deems it good [like one who is rightly guided]? It is Allah who causes to stray whom He wills and guides whom He wills. So do not let yourself collapse in grief for them. Allah is All-Knowing of what they do.
