سُنَّةَ اللَّهِ الَّتِي قَدْ خَلَتْ مِن قَبْلُ وَلَن تَجِدَ لِسُنَّةِ اللَّهِ تَبْدِيلًا
[48:23]
Such has been the course of Allah that has indeed run before, and you shall not find a change in Allah's course.
(Such has been) the practice (approved) of Allah already in the past: no change wilt thou find in the practice (approved) of Allah.
It is the law of Allah which hath taken course aforetime. Thou wilt not find for the law of Allah aught of power to change.
