"Remember when your Lord said to you, 'If you give thanks, I shall give you greater (favors), but if you deny the Truth, know that My retribution is severe ". 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Have you not heard what befell the nations that have gone before you? The nations of Noah, Aad, and Thamood, and those who came after? None knows them but Allah. Their Messengers came to them with clear signs, but they thrust their hands into their mouths and said: 'Without doubt we disbelieve the Message you have been sent with. That which you call us to is 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 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
