Remember, your Lord proclaimed: "I shall give you more if you are grateful; but if you are thankless then surely My punishment is very great." 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, 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 Noble Messengers said, “What! You doubt concerning Allah, the Creator of the heavens and the earth? He calls you that He may forgive some of your sins and until the time of death give you a life free from punishment”; they said, “You are just human beings like us; you wish to prevent us from what our forefathers used to worship – therefore now bring some clear proof to us.” 10 Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the believers 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
