And when your Lord proclaimed: If ye give thanks, I will give you more; but if ye are thankless, lo! My punishment is dire. 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 any doubt about Allah, the Originator of the heavens and the earth? He calls you to Him in order that He forgives you your sins and defers you till a stated term' They said: 'You are only mortals like us. You wish to bar us from that which our fathers worshipped. Give us some clear proof.' 10 Their messengers said to them: "True, we are human like yourselves, but Allah doth grant His grace to such of his servants as He pleases. It is not for us to bring you an authority except as Allah permits. And on Allah let all men of faith put their trust. 11 Why should we not trust in God when He has shown us the right way? We shall exercise patience against the troubles with which you afflict us. Whoever needs a trustee should trust in God." 12
