And when your Lord proclaimed: "If you give thanks, I will increase you, but, if you are unthankful My punishment is indeed stern.' 7 And Moses said: 'If you and all mankind are thankless, He is surely Rich, 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 ۞ Their messengers said, "Can there be doubt about Allah, Creator of the heavens and earth? He invites you that He may forgive you of your sins, and He delays your death for a specified term." They said, "You are not but men like us who wish to avert us from what our fathers were worshipping. So bring us a clear authority." 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
