And indeed, We sent Our messages unto people before thy time, [O Prophet,] and visited them with misfortune and hardship so that they might humble themselves: 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 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 So the last remnant of the people who did evil was cut off. Praise belongs to God the Lord of all Being. 45 Say, "If God should take away your hearing and your sight and seal your hearts, who is the deity who could restore it to you save God?" See how We explain the signs to them in diverse ways, yet they turn away. 46 Say: "Can you imagine what your condition will be if God's chastisement befalls you, either suddenly or in a [gradually] perceptible manner? [But then - ] will any but evildoing folk [ever] be destroyed? 47 We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve. 48 But those who reject our signs,- them shall punishment touch, for that they ceased not from transgressing. 49 Say (O Muhammad SAW): "I don't tell you that with me are the treasures of Allah, nor (that) I know the unseen; nor I tell you that I am an angel. I but follow what is revealed to me by inspiration." Say: "Are the blind and the one who sees equal? will you not then take thought?" 50
