الاسراۤء — Al-Isra' Ayat 54
رَبُّكُمْ اَعْلَمُ بِكُمْ اِنْ يَّشَأْ يَرْحَمْكُمْ اَوْ اِنْ يَّشَأْ يُعَذِّبْكُمْۗ وَمَآ اَرْسَلْنٰكَ عَلَيْهِمْ وَكِيْلًا
Rabbukum a‘lamu bikum, iy yasya' yarḥamkum au iy yasya' yu‘ażżibkum, wa mā arsalnāka ‘alaihim wakīlā(n).
"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."
