And [remember the time] when your Sustainer made [this promise] known: 'If you are grateful [to Me,] I shall most certainly give you more and more; but if you are ungrateful, verily, My chastisement will be severe indeed!"' 7 And Musa said: if ye disbelive, ye and all those who are on the earth - then verily Allah is Self-Sufficient, Praiseworthy. 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 ۞ 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 why should we not put our trust in God, seeing that He has guided us in our ways? We will surely endure patiently, whatever you hurt us; and in God let all put their trust who put their trust.' 12
