And when your Lord proclaimed, "If you are thankful, surely I will increase you, but if you are thankless My chastisement is surely terrible."' 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)." 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 replied, "We are indeed mortals like yourselves. But God bestows His grace on such of His servants as He chooses. We cannot give you miracles, except by God's leave. In God let true believers put their trust -- 11 And how could we not place our trust in God, seeing that it is He who has shown us the path which we are to follow? "Hence, we shall certainly bear with patience whatever hurt you may do us: for, all who have trust [in His existence] must place their trust in God [alone]!" 12
