Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 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 And when they had forgotten that with which they have been admonished, We opened the gates of everything to them, until just as they were rejoicing in what they were given, We suddenly seized them and they were in utter despair. 44 Of the wrong-doers the last remnant was cut off. Praise be to Allah, the Cherisher of the worlds. 45 Say: Have you considered that if Allah takes away your hearing and your sight and sets a seal on your hearts, who is the god besides Allah that can bring it to you? See how We repeat the communications, yet they turn away. 46 Say: 'What think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 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 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 possess the treasuries of God"; I know not the Unseen. And I say not to you, "I am an angel"; I only follow what is revealed to me. Say: 'Are the blind and the seeing man equal? Will you not reflect?' 50
