And when your Lord proclaimed, "If you are thankful, surely I will increase you, but if you are thankless My chastisement is surely terrible."' 7 And Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, 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 messengers said: "Is there a doubt about Allah, The Creator of the heavens and the earth? It is He Who invites you, in order that He may forgive you your sins and give you respite for a term appointed!" They said: "Ah! ye are no more than human, like ourselves! Ye wish to turn us away from the (gods) our fathers used to worship: then bring us some clear authority." 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 wherefore should we not rely on Allah when He hath surely guided us our ways! And surely we shall bear patiently that with which ye afflict us and in Allah then let the trustful put their trust. 12
