Verily, We sent (Messengers) to many nations before you (O Muhammad SAW). And We seized them with extreme poverty (or loss in wealth) and loss in health with calamities so that they might believe with humility. 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 So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair. 44 As such the harmdoers were annihilated. Praise be to Allah, Lord of the Worlds! 45 (Muhammad), ask them, "Have you ever considered that if God was to disable your hearing and vision and veil your hearts, could anyone besides Him restore them?" Look at how plainly We show them the evidence (of the Truth) but they always ignore it. 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 But as for those who deny Our revelations, torment will afflict them for that they used to disobey. 49 Say: I do not say to you, I have with me the treasures of Allah, nor do I know the unseen, nor do I say to you that I am an angel; I do not follow aught save that which is revealed to me. Say: Are the blind and the seeing one alike? Do you not then reflect? 50
