And indeed We sent Noble Messengers before you, and made wives and children for them; and it is not the task of any Noble Messenger to bring a sign except by Allah’s command; and all promises have a time prescribed. 38 Allah doth blot out or confirm what He pleaseth: with Him is the Mother of the Book. 39 BUT WHETHER We let thee see [in thy lifetime, O Prophet, the fulfilment of] some of what We have promised them, or whether We cause thee to die [before its fulfilment] - thy duty is no more than to deliver the message; and the reckoning is Ours. 40 See they not that We gradually reduce the land (of disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning. 41 Those who have gone before them devised, but to Allah is the devising altogether. He knows what every soul earns. The unbelievers shall know without doubt for whom is the Ultimate Abode. 42 The unbelievers claim that you have not been sent by Allah. Tell them: "Allah is sufficient as a witness between me and you; and so also do those who know the Scriptures." 43
