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 Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Have the accounts of your predecessors not reached you: the people of Noah, the Ad, the Thamud, and those who came after them - they whose number is not known to any except Allah? Their Messengers came to them with Clear Signs, but they thrust their hands in their mouths, and said: "We do surely reject the Message you have brought, and we are in disquieting doubt about what you are summoning us to." 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 told them: "Indeed we are only human beings like yourselves, but Allah bestows His favour on those of His servants whom He wills. It does not lie in our power to produce any authority except by the leave of Allah. It is in Allah that the believers should put their trust. 11 And why should we not rely upon Allah while He has guided us to our [good] ways. And we will surely be patient against whatever harm you should cause us. And upon Allah let those who would rely [indeed] rely." 12
