الاسراۤء — Al-Isra' Ayat 77

سُنَّةَ مَنْ قَدْ اَرْسَلْنَا قَبْلَكَ مِنْ رُّسُلِنَا وَلَا تَجِدُ لِسُنَّتِنَا تَحْوِيْلًا ࣖ

Sunnata man qad arsalnā qablaka mir rusulinā wa lā tajidu lisunnatinā taḥwīlā(n).

"[That is Our] established way for those We had sent before you of Our messengers; and you will not find in Our way any alteration."
