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 ye show ingratitude, ye and all on earth together, yet is Allah free of all wants, worthy of all praise. 8 Has there not reached you the news of those before you - the people of Noah and 'Aad and Thamud and those after them? No one knows them but Allah. Their messengers brought them clear proofs, but they returned their hands to their mouths and said, "Indeed, we disbelieve in that with which you have been sent, and indeed we are, about that to which you invite us, in disquieting doubt." 9 ۞ Their Messengers said, 'Is there any doubt regarding God, the Originator of the heavens and the earth, who calls you so that He may forgive you your sins, and defer you to a term stated?' They said, 'You are nothing but mortals, like us; you desire to bar us from that our fathers served; then bring us a manifest authority.' 10 The Messengers replied, "We are certainly mere mortals like you, but God bestows His favors on whichever of His servants He wants. We can not bring you authority without the permission of God. The faithful should trust in God alone. 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
