"Remember when your Lord said to you, 'If you give thanks, I shall give you greater (favors), but if you deny the Truth, know that My retribution is severe ". 7 And Moses said, 'If you are thankless, you and whoso is on earth, all together, yet assuredly God is All-sufficient, All-laudable.' 8 Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)." 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 wherefore should we not rely on Allah when He hath surely guided us our ways! And surely we shall bear patiently that with which ye afflict us and in Allah then let the trustful put their trust. 12
