Surah Al-Isra, Verse 54

رَّبُّكُمۡ أَعۡلَمُ بِكُمۡۖ إِن يَشَأۡ يَرۡحَمۡكُمۡ أَوۡ إِن يَشَأۡ يُعَذِّبۡكُمۡۚ وَمَآ أَرۡسَلۡنَٰكَ عَلَيۡهِمۡ وَكِيلٗا٥٤

rabbukum aʿlamu bikum in yasha yarḥamkum aw in yasha yuʿadhib'kum wamā arsalnāka ʿalayhim wakīlan

Your Lord is most knowing of you. If He wills, He will have mercy upon you; or if He wills, He will punish you. And We have not sent you, [O Muḥammad], over them as a manager.
