Remember also the time when your Lord declared, 'If you are grateful, I will surely bestow more favours on you; but if you are ungrateful, then know that My punishment is severe indeed.'" 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Has not news come to you concerning those who preceded you, such as Noah's people, and the 'Ad and Thamud, as well as those who came after them? Only God knows who they were. The messengers came to them with clear signs, but they put their hands to their mouths saying, "We deny the message you have been sent with. We have grave doubts about what you are inviting us to do." 9 ۞ The Messengers asked them, "Could there be any doubt about the existence of God who has created the heavens and the earth? He calls you to Himself to forgive your sins. He gives you respite only until the appointed time." They said, "You are mere mortals like us. What you want is to prevent us from worshipping that which our fathers worshipped. Show us clear proof (if what you say is true)." 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 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
