And [remember] when your Lord proclaimed, 'If you are grateful, I will surely increase you [in favor]; but if you deny, indeed, My punishment is severe.' " 7 And Musa said: If you are ungrateful, you and those on earth all together, most surely Allah is Self-sufficient, Praised; 8 Have you (believers) ever heard the news about those who lived before you, like the people of Noah, Ad, Thamud, and those who lived after them? No one knows about them except God. Messengers were sent to them with miracles, but they put their hands to their mouths and said, "We do not believe in whatever you preach and we are also doubtful and uncertain about that to which you invite us." 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 messengers replied, "We are indeed mortals like yourselves. But God bestows His grace on such of His servants as He chooses. We cannot give you miracles, except by God's leave. In God let true believers put their trust -- 11 How should we not put our trust in Allah when He hath shown us our ways? We surely will endure the hurt ye do us. In Allah let the trusting put their trust. 12
