And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.' " 7 And Moses said: "If ye show ingratitude, ye and all on earth together, yet is Allah free of all wants, worthy of all praise. 8 Hath not the history of those before you reached you: the folk of Noah, and (the tribes of) A'ad and Thamud, and those after them? None save Allah knoweth them. Their messengers came unto them with clear proofs, but they thrust their hands into their mouths, and said: Lo! we disbelieve in that wherewith ye have been sent, and lo! we are in grave doubt concerning that to which ye call 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 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 Allah while He indeed has guided us our ways. And we shall certainly bear with patience all the hurt you may cause us, and in Allah (Alone) let those who trust, put their trust." 12
