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 annuls or confirms whatever He wills [of His earlier messages] - for with Him is the source of all revelation. 39 Whether We let thee see something of that which We have promised them, or make thee die (before its happening), thine is but conveyance (of the message). Ours the reckoning. 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 Those who have gone before them devised, but to Allah is the devising altogether. He knows what every soul earns. The unbelievers shall know without doubt for whom is the Ultimate Abode. 42 They who disbelieve say: Thou art no messenger (of Allah). Say: Allah, and whosoever hath knowledge of the Scripture, is sufficient witness between me and you. 43
