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.

But if they turn aside, We have not sent you as a watcher over them; on you is only to deliver (the message); and surely when We make man taste mercy from Us, he rejoices thereat; and if an evil afflicts them on account of what their hands have already done, then-surely man is ungrateful.
