( سنة الله التي قد خلت من قبل ) أي كسنة الله في نصر أوليائه وقهر أعدائه ( ولن تجد لسنة الله تبديلا ) .
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.
