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 And We will either let you see part of what We threaten them with or cause you to die, for only the delivery of the message is (incumbent) on you, while calling (them) to account is Our (business). 40 Have they not considered that We have taken over the land and reduced its borders? It is God who issues the irreversible decree and His reckoning is swift. 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 Those who disbelieve say: 'You are not a Messenger' Say: 'Allah is a Sufficient witness between me and you, and whosoever possess knowledge of the Book' 43
