Al-Fath 48:23

Sunnata Allahi allatee qad khalat minqablu walan tajida lisunnati Allahi tabdeela

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

- according to the consistent practice of Allah that went on since before, and you will never find a change in Allah’s consistent practice.
