And We did indeed send Messengers to other nations before you and then We seized those nations with misfortune and hardship so that they might humble themselves (before Us). 42 So why did they not humbly plead when Our punishment came to them? But their hearts were hardened and the devil made all their deeds appear good 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 The wrongdoers were thus annihilated. All praise be to God, the Lord of the Worlds. 45 Say: 'What think you? If God seizes your hearing and sight, and sets a seal upon your hearts, who is a god other than God to give it back to you?' Behold how We turn about the signs! Yet thereafter they are turning away. 46 Say, “What is your opinion – if the punishment of Allah were to come upon you suddenly or openly (with forewarning), who would be destroyed except the disbelieving people?” 47 And We send not the messengers except as bringers of good tidings and warners. So whoever believes and reforms - there will be no fear concerning them, nor will they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
