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 Allah blots out what He wills and confirms (what He wills). And with Him is the Mother of the Book (Al-Lauh Al-Mahfuz) 39 Whether We show you (O Muhammad SAW) part of what We have promised them or cause you to die, your duty is only to convey (the Message) and on Us is the reckoning. 40 See they not that We gradually reduce the land (in their control) from its outlying borders? (Where) Allah commands, there is none to put back His Command: and He is swift in calling to account. 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
