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 Moses said, 'If you are thankless, you and whoso is on earth, all together, yet assuredly God is All-sufficient, All-laudable.' 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 Messengers said: "Can there be any doubt about Allah, the Creator of the heavens and the earth? He invites you that He may forgive you your sins and grant you respite till an appointed term." They replied: "You are only a human being like ourselves. You seek to prevent us from serving those whom our forefathers have been serving all along. If that is so, produce a clear authority for it." 10 Their messengers replied, "We are indeed mortals like yourselves. But God bestows His grace on such of His servants as He chooses. We cannot give you miracles, except by God's leave. In God let true believers 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
