And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 42 yet when the misfortune decreed by Us befell them, they did not humble themselves, but rather their hearts grew hard, for Satan had made all their doings seem goodly to them. 43 When they had forgotten Our admonition, We granted them all that they desired; but just as they were rejoicing in what they were given, We seized them suddenly and they were plunged into despair. 44 So the people that committed wrong were eliminated. And praise to Allah, Lord 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 thou look ye now, were Allah's torment to come upon you on a sudden or openly, would there be destroyed any but the wrong-doers? 47 We do not send apostles but to give good tidings and to warn. Then those who believe or reform will have neither fear nor regret. 48 Those who reject Our revelations will certainly be punished for their evil deeds. 49 (O Muhammad!) Say: 'I do not say to you I have the treasures of Allah. Nor do I have knowledge of what is beyond the reach of human perception. Nor do I say to you: I am an angel. I only follow what is revealed to me.' Then ask them: 'Are the blind and the seeing alike?' Do you not then reflect? 50
