Remember also the time when your Lord declared, 'If you are grateful, I will surely bestow more favours on you; but if you are ungrateful, then know that My punishment is severe indeed.'" 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 there not come to you the tidings of those who were before you -- the people of Noah, Ad, Thamood, and of those after them whom none knows but God? Their Messengers came to them with the clear signs; but they thrust their hands into their mouths, saying, 'We certainly disbelieve in the Message you have been sent with, and we are in doubt, concerning that you call us unto, disquieting.' 9 ۞ Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority." 10 Their messengers said to them: "True, we are human like yourselves, but Allah doth grant His grace to such of his servants as He pleases. It is not for us to bring you an authority except as Allah permits. And on Allah let all men of faith put 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
