Surah Al-Ahzab, ayah 62

سُنَّةَ ٱللَّهِ فِي ٱلَّذِينَ خَلَوۡاْ مِن قَبۡلُۖ وَلَن تَجِدَ لِسُنَّةِ ٱللَّهِ تَبۡدِيلٗا ٦٢

Sunnatallāhi fil-ladhīna khalaw min qablu walan tajida lisunnatillāhi tabdīlā

[This is] the established way of Allāh with those who passed on before; and you will not find in the way of Allāh any change.
