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 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 (the warning) with which they had been reminded, We opened to them the gates of every (pleasant) thing, until in the midst of their enjoyment in that which they were given, all of a sudden, We took them to punishment, and lo! They were plunged into destruction with deep regrets and sorrows. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher of the worlds. 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 46 Say: 'If the chastisement of Allah were to overtake you unawares or openly shall any except the wrong-doing people be destroyed?' 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 But those who belie Our verses, punishment shall touch them for their misdeeds. 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
