And remember! your Lord caused to be declared (publicly): "If ye are grateful, I will add more (favours) unto you; But if ye show ingratitude, truly My punishment is terrible indeed." 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 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 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 unto them: We are but mortals like you, but Allah giveth grace unto whom He will of His slaves. It is not ours to bring you a warrant unless by the permission of Allah. In Allah let believers put their trust! 11 And why should we not put our trust in Allah, when He has already guided us to our Paths? We will endure your hurt patiently. In Allah, let all who trust place their trust' 12
