Surah Al-Fatir (The Originator), Verse 8

اَفَمَنْ زُیِّنَ لَهٗ سُوْٓءُ عَمَلِهٖ فَرَاٰهُ حَسَنًا فَاِنَّ اللّٰهَ یُضِلُّ مَنْ یَّشَآءُ وَیَهْدِیْ مَنْ یَّشَآءُ فَلَا تَذْهَبْ نَفْسُكَ عَلَیْهِمْ حَسَرٰتٍ اِنَّ اللّٰهَ عَلِیْمٌۢ بِمَا یَصْنَعُوْنَ ۟

Afaman zuyyina lahoo sooo'u 'amalihee fara aahu hasanaa; fa innal laaha yudillu mai yashaaa'u wa yahdee mai yashaaa'u falaa tazhab nafsuka 'alaihim hasaraat; innal laaha 'aleemun bimaa yasna'oon

“Is he, then, to whom the evil of his conduct is made alluring, so that he looks upon it as good, (equal to one who is rightly guided)? For Allah leaves to stray whom He wills, and guides whom He wills. So let not thy soul go out in (vainly) sighing after them: for Allah knows well all that they do!”
