Indeed We sent to nations before thee, and We seized them with misery and hardship that haply they might be humble; 42 Then why, when Our punishment came to them, did they not humble themselves? But their hearts became hardened, and Satan made attractive to them that which they were doing. 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 Then the people who committed wrong were cut off completely. And all praise is unto Allah, the 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: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust people? 47 We send the messengers only to give good news and to warn: so those who believe and mend (their lives),- upon them shall be no fear, nor shall they grieve. 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 Say thou: I say not unto you, that with me are the treasures of Allah, nor I know the Unseen, nor say unto you that I am an angel; I but follow that which hath been revealed unto me. Say thou: are the blind and the seeing equal? Will ye not then consider? 50
