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 you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Have you (believers) ever heard the news about those who lived before you, like the people of Noah, Ad, Thamud, and those who lived after them? No one knows about them except God. Messengers were sent to them with miracles, but they put their hands to their mouths and said, "We do not believe in whatever you preach and we are also doubtful and uncertain about that to which you invite us." 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 messengers said to them: "True, we are human like yourselves, but Allah doth grant His grace to such of his servants as He pleases. It is not for us to bring you an authority except as Allah permits. And on Allah let all men of faith 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
