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 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 apostles said: is there doubt about Allah, the Maker of the heavens and the earth? He calleth you that he may forgive you of your sins and retain you till a term fixed. They said: ye are but like us; ye mean to turn us aside from that which our fathers have been worshipping; so bring us a warranty manifest. 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 and why should we not put our trust in God when He has already guided us to our paths? We will, surely, bear with patience all the harm you do us. So in God let those who trust put their trust." 12
