Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 Then why did they not submit when Our punishment came upon them? But their hearts were hardened, and Satan made things they were doing look attractive to them. 43 So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair. 44 So of the people who did wrong the last remnant was cut off. Praise be to Allah, Lord of the Worlds! 45 Say (O Muhammad!): What do you think? If Allah should take away your hearing and your sight and seal your hearts - who is the god, other than Allah, who could restore them to you? Behold, how We put forth Our signs in diverse forms, and yet they turn away from them. 46 Say: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 And We send not the sent ones except as bearers of glad tidings and warners. Then whosoever believeth and amendeth, on such shall come no fear nor they shall grieve. 48 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 49 Say (O Muhammad, to the disbelievers): I say not unto you (that) I possess the treasures of Allah, nor that I have knowledge of the Unseen; and I say not unto you: Lo! I am an angel. I follow only that which is inspired in me. Say: Are the blind man and the seer equal? Will ye not then take thought? 50
