سُنَّةَ مَن قَدْ أَرْسَلْنَا قَبْلَكَ مِن رُّسُلِنَا وَلاَ تَجِدُ لِسُنَّتِنَا تَحْوِيلاً
[17:77]
(This is Our) course with regard to those of Our messengers whom We sent before you, and you shall not find a change in Our course.
(This was Our) way with the messengers We sent before thee: thou wilt find no change in Our ways.
(Such was Our) method in the case of those whom We sent before thee (to mankind), and thou wilt not find for Our method aught of power to change.
