We sent down messengers before you and gave them wives and children. Yet it was not possible for a messenger to bring a sign, save by the command of God. Every age has had its revelation. 38 For every event God has ordained His decree. God establishes or effaces whatever He wants and with Him is the original of the Book. 39 Whether We shall show thee (within thy life-time) part of what we promised them or take to ourselves thy soul (before it is all accomplished),- thy duty is to make (the Message) reach them: it is our part to call them to account. 40 Do they not see how We come to the land and reduce its extremities? Allah judges; none repel His judgement. Swift is His reckoning. 41 And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination). 42 And those who disbelieve say: You are not a messenger. Say: Allah is sufficient as a witness between me and you and whoever has knowledge of the Book. 43
