For his sake there are angels following one another, before him and behind him, who guard him by Allah's commandment; surely Allah does not change the condition of a people until they change their own condition; and when Allah intends evil to a people, there is no averting it, and besides Him they have no protector.

And We gave them clear arguments in the affair, but they did not differ until after knowledge had come to them out of envy among themselves; surely your -Lord will judge between them on the day of resurrection concerning that wherein they differed.
