Surah Al-Fath, Verse 23

سُنَّةَ ٱللَّهِ ٱلَّتِي قَدۡ خَلَتۡ مِن قَبۡلُۖ وَلَن تَجِدَ لِسُنَّةِ ٱللَّهِ تَبۡدِيلٗا٢٣

sunnata l-lahi allatī qad khalat min qablu walan tajida lisunnati l-lahi tabdīlan

[This is] the established way of Allāh which has occurred before. And never will you find in the way of Allāh any change.
