And when your Lord proclaimed: "If you give thanks, I will increase you, but, if you are unthankful My punishment is indeed stern.' 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Has there not come to you the tidings of those who were before you -- the people of Noah, Ad, Thamood, and of those after them whom none knows but God? Their Messengers came to them with the clear signs; but they thrust their hands into their mouths, saying, 'We certainly disbelieve in the Message you have been sent with, and we are in doubt, concerning that you call us unto, disquieting.' 9 ۞ Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority." 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 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
