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 Moses said: 'If you and all mankind are thankless, He is surely Rich, Praised' 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: "Can there be any doubt about Allah, the Creator of the heavens and the earth? He invites you that He may forgive you your sins and grant you respite till an appointed term." They replied: "You are only a human being like ourselves. You seek to prevent us from serving those whom our forefathers have been serving all along. If that is so, produce a clear authority for it." 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 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
