And certainly We sent apostles before you and gave them wives and children, and it is not in (the power of) an apostle to bring a sign except by Allah's permission; for every term there is an appointment. 38 God abrogates or confirms what He pleases; with Him is the source of all commandments. 39 And whether We shew thee part of that which We have promised them, or We take thee away; on thee is only the preaching, and on Us is the reckoning. 40 Behold they not that We visit the land diminishing it by the borders; thereof Allah judgeth, and there is no reviser of His judgment, and He is swift in reckoning, 41 Certain people who lived before plotted evil plans but God is the Master of all plans. He knows what every soul does. The unbelievers will soon learn who will achieve the blissful end. 42 The unbelievers say, 'Thou art not an Envoy.' Say: 'God suffices as a witness between me and you, and whosoever possesses knowledge of the Book.' 43
