And when your Lord made it known: If you are grateful, I would certainly give to you more, and if you are ungrateful, My chastisement is truly 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 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 about Allah, the Originator of the heavens and the earth? He calls you to Him in order that He forgives you your sins and defers you till a stated term' They said: 'You are only mortals like us. You wish to bar us from that which our fathers worshipped. Give us some clear proof.' 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 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
