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 Moses told his people, "If you and everyone on the earth turn to disbelief, know that God is Self-sufficient and Praiseworthy." 8 Has not the news of those before you, the people of Noah and 'Ad and Thamud, and those who came after them, come to you? None knows (about) them except God. Their apostles came to them with clear proofs, but they tried to silence them and said: "We do not believe in what you have been sent with, and we are in doubt of what you call us to, about which we are in disquiet.' 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 unto them: We are but mortals like you, but Allah giveth grace unto whom He will of His slaves. It is not ours to bring you a warrant unless by the permission of Allah. In Allah let believers 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
