Remember also the time when your Lord declared, 'If you are grateful, I will surely bestow more favours on you; but if you are ungrateful, then know that My punishment is severe indeed.'" 7 And Moses said: "If ye show ingratitude, ye and all on earth together, yet is Allah free of all wants, worthy of all praise. 8 Have you not heard what befell the nations that have gone before you? The nations of Noah, Aad, and Thamood, and those who came after? None knows them but Allah. Their Messengers came to them with clear signs, but they thrust their hands into their mouths and said: 'Without doubt we disbelieve the Message you have been sent with. That which you call us to is disquieting' 9 ۞ Their Messengers said, 'Is there any doubt regarding God, the Originator of the heavens and the earth, who calls you so that He may forgive you your sins, and defer you to a term stated?' They said, 'You are nothing but mortals, like us; you desire to bar us from that our fathers served; then bring us a manifest authority.' 10 Their Messengers said to them: 'We are nothing except humans like you. But Allah bestows His Mercy on those of His worshipers whom He chooses. We cannot give you proof, except with the permission of Allah. In Allah, let believers put their trust. 11 Why should we not trust in God when He has shown us the right way? We shall exercise patience against the troubles with which you afflict us. Whoever needs a trustee should trust in God." 12
