And when your Lord made it known: If you are grateful, I would certainly give to you more, and if you are ungrateful, My chastisement is truly severe. 7 And Moses said: "If ye show ingratitude, ye and all on earth together, yet is Allah free of all wants, worthy of all praise. 8 Have you (believers) ever heard the news about those who lived before you, like the people of Noah, Ad, Thamud, and those who lived after them? No one knows about them except God. Messengers were sent to them with miracles, but they put their hands to their mouths and said, "We do not believe in whatever you preach and we are also doubtful and uncertain about that to which you invite us." 9 ۞ Their messengers said: Can there be doubt concerning Allah, the Creator of the heavens and the earth? He calleth you that He may forgive you your sins and reprieve you unto an appointed term. They said: Ye are but mortals like us, who would fain turn us away from what our fathers used to worship. Then bring some clear warrant. 10 Their apostles said to them: We are nothing but mortals like yourselves, but Allah bestows (His) favors on whom He pleases of His servants, and it is not for us that we should bring you an authority except by Allah's permission; and on Allah should the believers rely. 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
