[This is] the established way of Allah which has occurred before. And (48:23)

﴿سُنَّةَ اللَّهِ الَّتِي قَدْ خَلَتْ مِن قَبْلُ ۖ وَلَن تَجِدَ لِسُنَّةِ اللَّهِ تَبْدِيلًا﴾
[ الفتح: 23]

48:23 [This is] the established way of Allah which has occurred before. And never will you find in the way of Allah any change.

The believers being victorious and consequent defeat of the disbelievers is established in every place and era; it is a divine custom of Allah prevalent in the nations that have passed before these rejectors.
O Messenger! You will not find any change in the divine custom of Allah.

That has been the Way of Allah already with those who passed away before. And you will not find any change in the Way of Allah.
