And remember! your Lord caused to be declared (publicly): "If ye are grateful, I will add more (favours) unto you; But if ye show ingratitude, truly My punishment is terrible indeed." 7 And Moosa said, “If you and all who are in the earth turn disbelievers, then indeed Allah is definitely Independent (Unwanting), Most Praiseworthy.” 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 apostles answered them: "True, we are nothing but mortal men like yourselves: but God bestows His favour upon whomever He wills of His servants. Withal, it is not within our power to bring you a proof [of our mission,] unless it be by God's leave - and [so] it is in God that all believers must place 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
