We have sent already unto peoples that were before thee, and We visited them with tribulation and adversity, in order that they might grow humble. 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 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 The wrongdoers were thus annihilated. All praise be to God, the Lord of the Worlds. 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: "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 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 whereas those who give the lie to Our signs, chastisement will visit them for their transgression. 49 Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "can the blind be held equal to the seeing?" Will ye then consider not? 50
