Remember, your Lord proclaimed: "I shall give you more if you are grateful; but if you are thankless then surely My punishment is very great." 7 And Moses said: 'If you and all mankind are thankless, He is surely Rich, Praised' 8 Has not the news of those before you, the people of Noah and 'Ad and Thamud, and those who came after them, come to you? None knows (about) them except God. Their apostles came to them with clear proofs, but they tried to silence them and said: "We do not believe in what you have been sent with, and we are in doubt of what you call us to, about which we are in disquiet.' 9 ۞ The Messengers asked them, "Could there be any doubt about the existence of God who has created the heavens and the earth? He calls you to Himself to forgive your sins. He gives you respite only until the appointed time." They said, "You are mere mortals like us. What you want is to prevent us from worshipping that which our fathers worshipped. Show us clear proof (if what you say is true)." 10 Their Messengers told them: "Indeed we are only human beings like yourselves, but Allah bestows His favour on those of His servants whom He wills. It does not lie in our power to produce any authority except by the leave of Allah. It is in Allah that the believers should put their trust. 11 And why should we not rely upon Allah while He has guided us to our [good] ways. And we will surely be patient against whatever harm you should cause us. And upon Allah let those who would rely [indeed] rely." 12
