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 Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, Praiseworthy. 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 ۞ Their Noble Messengers said, “What! You doubt concerning Allah, the Creator of the heavens and the earth? He calls you that He may forgive some of your sins and until the time of death give you a life free from punishment”; they said, “You are just human beings like us; you wish to prevent us from what our forefathers used to worship – therefore now bring some clear proof to us.” 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 what reason have we that we should not rely on Allah? And He has indeed guided us in our ways; and certainly we would bear with patience your persecution of us; and on Allah should the reliant rely. 12
