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 Moses told his people, "If you and everyone on the earth turn to disbelief, know that God is Self-sufficient and Praiseworthy." 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 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 apostles answered them: "True, we are nothing but mortal men like yourselves: but God bestows His favour upon whomever He wills of His servants. Withal, it is not within our power to bring you a proof [of our mission,] unless it be by God's leave - and [so] it is in God that all believers must place their trust. 11 And what reason have we that we should not rely on Allah? And He has indeed guided us in our ways; and certainly we would bear with patience your persecution of us; and on Allah should the reliant rely. 12
