سُنَّةَ اللَّهِ فِي الَّذِينَ خَلَوْا مِن قَبْلُ وَلَن تَجِدَ لِسُنَّةِ اللَّهِ تَبْدِيلًا
[33:62]
(Such has been) the course of Allah with respect to those who have gone before; and you shall not find any change in the course of Allah.
(Such was) the practice (approved) of Allah among those who lived aforetime: No change wilt thou find in the practice (approved) of Allah.
That was the way of Allah in the case of those who passed away of old; thou wilt not find for the way of Allah aught of power to change.
