And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 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 of the people who did wrong the last remnant was cut off. Praise be 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: Have you considered if the chastisement of Allah should overtake you suddenly or openly, will any be destroyed but the unjust 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 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 49 Tell them: "I do not say that I possess the treasures of God, or have knowledge of the Unknown, or that I am an angel. I only follow what is sent down to me." And say: "How can a blind man and a man who can see, be alike? Will you not reflect?" 50
