Sura Yūsuf 12:52

ذَٰلِكَ لِيَعْلَمَ أَنِّى لَمْ أَخُنْهُ بِٱلْغَيْبِ وَأَنَّ ٱللَّـهَ لَا يَهْدِى كَيْدَ ٱلْخَآئِنِينَ

dhālika li-yaʿlama annī lam akhunhu bil-ghaybi wa-anna allāha lā yahdī kayda l-khāʾinīna

"This (say I), in order that He may know that I have never been false to him in his absence, and that Allah will never guide the snare of the false ones.
