And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.' " 7 And Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, Praiseworthy. 8 Has not the account reached you of those before you, of the people of Nuh and Ad and Samood, and those after them? None knows them but Allah. Their apostles come to them with clear arguments, but they thrust their hands into their mouths and said: Surely we deny that with which you are sent, and most surely we are in serious doubt as to that to which you invite us. 9 ۞ Their messengers said, "Is there any doubt about God, the Originator of the heavens and earth? He calls you to Him in order to forgive you some of your offences and to reprieve you for a specific period." They said, "You are only human beings like ourselves! You want to divert us from what our forefathers have been worshipping, so bring us some clear 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
