Qur'an 35:8

أَفَمَن زُيِّنَ لَهُۥ سُوٓءُ عَمَلِهِۦ فَرَءَاهُ حَسَنًا ۖ فَإِنَّ ٱللَّهَ يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۖ فَلَا تَذْهَبْ نَفْسُكَ عَلَيْهِمْ حَسَرَٰتٍ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَصْنَعُونَ

Is he, the evil of whose deeds is made fairseeming unto him so that he deemeth it good, (other than Satan's dupe)? Allah verily sendeth whom He will astray, and guideth whom He will; so let not thy soul expire in sighings for them. Lo! Allah is Aware of what they do!
