And We sent Messengers before thee, and We assigned to them wives, and seed; and it was not for any Messengers to bring a sign, but by God's leave. Every term has a Book. 38 Allah blots out, and He establishes what He will. With Him is the Essence 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 Do they not see how We come to [their] land and shrink its borders? God decides, no one can reverse His decision, 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 And those who disbelieve say: thou art not a sent one. Say thou: Allah is a sufficient witness between me and you, and also he with whom is knowledge of the Book. 43
