And when your Lord made it known: If you are grateful, I would certainly give to you more, and if you are ungrateful, My chastisement is truly severe. 7 And Moses said: "If ye show ingratitude, ye and all on earth together, yet is Allah free of all wants, worthy of all praise. 8 HAVE THE STORIES of those [deniers of the truth] who lived before you never yet come within your ken - [the stories of] the people of Noah, and of [the tribes of] 'Ad and Thamud, and of those who came after them? None knows them [now] save God. There came unto them their apostles with all evidence of the truth - but they covered their mouths with their hands and answered: "Behold, we refuse to regard as true the message with which you [claim to] have been entrusted; and behold, we are in grave doubt, amounting to suspicion, about [the meaning of] your call to 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 said to them, 'We are nothing but mortals, like you; but God is gracious unto whomsoever He will of His servants. It is not for us to bring you an authority save by the leave of God; and in God let the believers put all 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
