We have indeed sent (apostles) to many a people before you, and inflicted upon them hardships and afflictions so that they might submit. 42 If only, when Our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto 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: "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: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust 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 deny Our messages will be seized by nemesis for being disobedient. 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
