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 Did not the tidings of those before you reach you? The people of Nooh, and the A’ad and the Thamud, and those after them? Only Allah knows them; their Noble Messengers came to them with clear proofs, they therefore raised their hands towards their own mouths, and said, “We disbelieve in what you have been sent with, and we are in a deeply intriguing doubt regarding the path you call us to.” 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, '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 Allah, when He has already guided us to our Paths? We will endure your hurt patiently. In Allah, let all who trust place their trust' 12
