And remember! your Lord caused to be declared (publicly): "If ye are grateful, I will add more (favours) unto you; But if ye show ingratitude, truly My punishment is terrible indeed." 7 And Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, Praiseworthy. 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, "Is there any doubt about God, the Originator of the heavens and earth? He calls you to Him in order to forgive you some of your offences and to reprieve you for a specific period." They said, "You are only human beings like ourselves! You want to divert us from what our forefathers have been worshipping, so bring us some clear authority." 10 Their Messengers told them: "Indeed we are only human beings like yourselves, but Allah bestows His favour on those of His servants whom He wills. It does not lie in our power to produce any authority except by the leave of Allah. It is in Allah that the believers should put their trust. 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
