We have sent already unto peoples that were before thee, and We visited them with tribulation and adversity, in order that they might grow humble. 42 So why did they not humbly plead when Our punishment came to them? But their hearts were hardened and the devil made all their deeds appear good to them! 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 So the people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say: 'What would you see if Allah took away your hearing and your sight, and set a seal upon your hearts, who is a god, other than Allah, to bring it back to you' Look how We make plain to them Our verses, and yet they turn away. 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 And We send not apostles but as announcers of good news and givers of warning, then whoever believes and acts aright, they shall have no fear, nor shall they grieve. 48 But as for those who deny Our revelations, torment will afflict them for that they used to disobey. 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
