And when your Lord proclaimed, "If you are thankful, surely I will increase you, but if you are thankless My chastisement is surely terrible."' 7 And Moses said, 'If you are thankless, you and whoso is on earth, all together, yet assuredly God is All-sufficient, All-laudable.' 8 Has there not reached you the news of those before you - the people of Noah and 'Aad and Thamud and those after them? No one knows them but Allah. Their messengers brought them clear proofs, but they returned their hands to their mouths and said, "Indeed, we disbelieve in that with which you have been sent, and indeed we are, about that to which you invite us, in disquieting doubt." 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 And why should we not put our trust in Allah when it is indeed He Who has guided us to the ways of our life? We shall surely continue to remain steadfast in face of your persecution. All those who have to put trust, should put their trust only in Allah." 12
