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 effaceth what He will, and establisheth (what He will), and with Him is the source of ordinance. 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 Do they not see that We are bringing destruction upon the land by curtailing it of its sides? And Allah pronounces a doom-- there is no repeller of His decree, and He is swift to take account. 41 Those who lived before them also devised many a plot, but the master plot rests with Allah. He knows what everyone does. The deniers of the truth will soon come to know whose end is good. 42 The unbelievers claim that you have not been sent by Allah. Tell them: "Allah is sufficient as a witness between me and you; and so also do those who know the Scriptures." 43
