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 you and all mankind are thankless, He is surely Rich, Praised' 8 Has there not come to you the tidings of those who were before you -- the people of Noah, Ad, Thamood, and of those after them whom none knows but God? Their Messengers came to them with the clear signs; but they thrust their hands into their mouths, saying, 'We certainly disbelieve in the Message you have been sent with, and we are in doubt, concerning that you call us unto, disquieting.' 9 ۞ Their Noble Messengers said, “What! You doubt concerning Allah, the Creator of the heavens and the earth? He calls you that He may forgive some of your sins and until the time of death give you a life free from punishment”; they said, “You are just human beings like us; you wish to prevent us from what our forefathers used to worship – therefore now bring some clear proof to us.” 10 Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the 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
