"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 Hath not the tidings come to you of those before you: the people of Nuh and the 'Aad and the Thamud and those after them! None knoweth them save Allah. There came unto them their apostles with the evidences, but they put their hands to their mouths, and said: verily we disbelieve in that wherewith ye have been sent, and verily regarding that to which ye call us we are in doubt disquieting. 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 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 And what reason have we that we should not rely on Allah? And He has indeed guided us in our ways; and certainly we would bear with patience your persecution of us; and on Allah should the reliant rely. 12
