Al-Isra 77

سُنَّةَ مَن قَدْ أَرْسَلْنَا قَبْلَكَ مِن رُّسُلِنَا ۖ وَلَا تَجِدُ لِسُنَّتِنَا تَحْوِيلًا

sunnata man qad arsalnā qablaka min rusulinā walā tajidu lisunnatinā taḥwīlan

[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.
