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 you are thankless, you and whoso is on earth, all together, yet assuredly God is All-sufficient, All-laudable.' 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: "What! Can there be a doubt about Allah, the Creator of the heavens and the earth? He calls you (to Monotheism and to be obedient to Allah) that He may forgive you of your sins and give you respite for a term appointed." They said: "You are no more than human beings like us! You wish to turn us away from what our fathers used to worship. Then bring us a clear authority i.e. a clear proof of what you say)." 10 Their messengers replied, "We are indeed mortals like yourselves. But God bestows His grace on such of His servants as He chooses. We cannot give you miracles, except by God's leave. In God let true believers 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
