Surah Al-Israa, Verse 54
رَّبُّكُمْ أَعْلَمُ بِكُمْ ۖ إِن يَشَأْ يَرْحَمْكُمْ أَوْ إِن يَشَأْ يُعَذِّبْكُمْ ۚ وَمَآ أَرْسَلْنَٰكَ عَلَيْهِمْ وَكِيلًۭا
Translation — Sahih International
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 Muhammad], over them as a manager.
