رَّبُّكُمۡ أَعۡلَمُ بِكُمۡۖ إِن يَشَأۡ يَرۡحَمۡكُمۡ أَوۡ إِن يَشَأۡ يُعَذِّبۡكُمۡۚ وَمَآ أَرۡسَلۡنَٰكَ عَلَيۡهِمۡ وَكِيلٗا
Wa qul li'ibaadee yaqoolul latee hiya ahsan; innash shaitaana yanzaghu bainahum; innash shaitaana kaana lil insaani 'aduwwam mubeenaa
It is your Lord that knoweth you best: If He please, He granteth you mercy, or if He please, punishment: We have not sent thee to be a disposer of their affairs for them.
— Al-Isra' (ٱلْإِسْرَاء), 17:54
