Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 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 When they had become oblivious of what they were warned, We opened wide the gates of everything to them; yet as they rejoiced at what they were given, We caught them unawares, and they were filled with despair. 44 So the roots of the people who were unjust were cut off; and all praise is due to Allah, the Lord of the worlds. 45 Say (O Muhammad!): What do you think? If Allah should take away your hearing and your sight and seal your hearts - who is the god, other than Allah, who could restore them to you? Behold, how We put forth Our signs in diverse forms, and yet they turn away from them. 46 Ask them, "Tell me, if the punishment of God came upon you suddenly or predictably, would any but the wrongdoers be destroyed?" 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 tell you that I have the treasuries of Allah or know the unseen, nor do I claim to be an angel. I follow only that which is revealed to me' Say: 'Are the blind and the seeing alike? Will you not think' 50
