And verily We sent messengers (to mankind) before thee, and We appointed for them wives and offspring, and it was not (given) to any messenger that he should bring a portent save by Allah's leave. For everything there is a time prescribed. 38 Allah effaces whatever He wills and retains whatever He wills. With Him is the Mother of the Book. 39 Whether We show you part of that We promise them, or We call you to Us, it is only for you to deliver the Message, and Ours is the accounting. 40 Have they not seen that We set upon the land, reducing it from its borders? And Allah decides; there is no adjuster of His decision. And He is swift in account. 41 Those who were before them plotted; but all plotting is Allah's. He knoweth that which each soul earneth. The disbelievers will come to know for whom will be the sequel of the (heavenly) Home. 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
