Indeed We sent to nations before thee, and We seized them with misery and hardship that haply they might be humble; 42 If only they humbled themselves when Our scourge overtook them! But their hearts were hardened, and satan decorated to them what they were doing. 43 Then when they forgot that whereof they were reminded We opened upon them the doors of everything, until when they boasted of that which they were given, We laid hold of them on a sudden, and lo! they were dumbfounded. 44 Then the people who committed wrong were cut off completely. And all praise is unto Allah, the Lord of the worlds. 45 Say: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away. 46 Say: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?" 47 We send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 48 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 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
