We sent many apostles before you, and bestowed on them wives and children, but it was not for any apostle to come up with a miracle unless by the leave of God. For every age there is a law. 38 God annuls or confirms whatever He wills [of His earlier messages] - for with Him is the source of all revelation. 39 (O Prophet), whether We make you see a part of the punishment that We have threatened them with come to pass during your life-time, or We take you away before that happens, your duty is no more than to convey the Message, and it is for Us to make a 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 And those before them had plotted, but to Allah belongs the plan entirely. He knows what every soul earns, and the disbelievers will know for whom is the final home. 42 And those who disbelieve, say: "You (O Muhammad SAW) are not a Messenger." Say: "Sufficient for a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)." 43
