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 added: "If you should [ever] deny the truth - you and whoever else lives on earth, all of you - [know that,] verily, God is indeed self-sufficient, ever to be praised!" 8 Has not the story reached you, (O people!), of those who (went) before you? - of the people of Noah, and 'Ad, and Thamud? - And of those who (came) after them? None knows them but Allah. To them came messengers with Clear (Signs); but they put their hands up to their mouths, and said: "We do deny (the mission) on which ye have been sent, and we are really in suspicious (disquieting) doubt as to that to which ye invite us." 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 but mortals, like you; but God is gracious unto whomsoever He will of His servants. It is not for us to bring you an authority save by the leave of God; and in God let the believers put all their trust. 11 And what reason have we that we should not rely on Allah? And He has indeed guided us in our ways; and certainly we would bear with patience your persecution of us; and on Allah should the reliant rely. 12
