We sent messengers before you [Prophet] to many communities and afflicted their people with suffering and hardship, so that they might humble themselves. 42 When the suffering reached them from us, why then did they not learn humility? On the contrary their hearts became hardened, and Satan made their (sinful) acts seem alluring 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 Then the people who committed wrong were cut off completely. And all praise is unto Allah, the 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: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 And We send not the Messengers but as givers of glad tidings and as warners. So whosoever believes and does righteous good deeds, upon such shall come no fear, nor shall they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 Say thou: I say not unto you, that with me are the treasures of Allah, nor I know the Unseen, nor say unto you that I am an angel; I but follow that which hath been revealed unto me. Say thou: are the blind and the seeing equal? Will ye not then consider? 50
