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 eliminates what He wills or confirms, and with Him is the Mother of the Book. 39 (O Prophet), whether We make you see a part of the punishment that We have threatened them with come to pass during your life-time, or We take you away before that happens, your duty is no more than to convey the Message, and it is for Us to make a reckoning. 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 And those before them had plotted, but to Allah belongs the plan entirely. He knows what every soul earns, and the disbelievers will know for whom is the final home. 42 The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book." 43
