Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 43 But when they neglected that with which they had been admonished, We opened for them the doors of all things, until when they rejoiced in what they were given We seized them suddenly; then lo! they were in utter despair. 44 Then the people who committed wrong were cut off completely. And all praise is unto Allah, 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 do you see yourselves then, if the punishment of Allah overtook you suddenly or openly, would any perish but the harmdoing nation' 47 We send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 48 But as for those who deny Our revelations, torment will afflict them for that they used to disobey. 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
