And certainly We sent (apostles) to nations before you then We seized them with distress and affliction in order that they might humble themselves. 42 yet when the misfortune decreed by Us befell them, they did not humble themselves, but rather their hearts grew hard, for Satan had made all their doings seem goodly to them. 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 did wrong were cut off. And all the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinns, and all that exists). 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: 'What think you? If God's chastisement comes upon you, suddenly or openly, shall any be destroyed, except the people of the evildoers?' 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 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
