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 Allah, the Originator of the heavens and the earth? He calls you to Him in order that He forgives you your sins and defers you till a stated term' They said: 'You are only mortals like us. You wish to bar us from that which our fathers worshipped. Give us some clear proof.' 10 Their Messengers said to them, 'We are nothing but mortals, like you; but God is gracious unto whomsoever He will of His servants. It is not for us to bring you an authority save by the leave of God; and in God let the believers put all their trust. 11 And why should we not put our trust in God, seeing that He has guided us in our ways? We will surely endure patiently, whatever you hurt us; and in God let all put their trust who put their trust.' 12
