We had sent (Our guidance) to the nations who lived before you and afflicted them with distress and adversity so that they might submit themselves (to God). 42 When the affliction decreed by Us befell them, they did not humble themselves, but rather their hearts hardened, for Satan had made all their doings seem fair to them. 43 But when they forgot the warning they had received, We opened to them the gates of all (good) things, until, in the midst of their enjoyment of Our gifts, on a sudden, We called them to account, when lo! they were plunged in despair! 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher 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 think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 47 We send the messengers only to give good news and to warn, so those who believe and reform themselves need have no fear, nor will they grieve. 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 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
