Al-Ahzab 62

سُنَّةَ ٱللَّهِ فِى ٱلَّذِينَ خَلَوْا۟ مِن قَبْلُ ۖ وَلَن تَجِدَ لِسُنَّةِ ٱللَّهِ تَبْدِيلًا

sunnata l-lahi fī alladhīna khalaw min qablu walan tajida lisunnati l-lahi tabdīlan

[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.
