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 If only, when Our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto them! 43 Then, when they forgot that whereof they had been reminded, We opened unto them the gates of all things till, even as they were rejoicing in that which they were given, We seized them unawares, and lo! they were dumbfounded. 44 So of the people who did wrong the last remnant was cut off. Praise be to Allah, Lord of the Worlds! 45 Say (O Muhammad!): What do you think? If Allah should take away your hearing and your sight and seal your hearts - who is the god, other than Allah, who could restore them to you? Behold, how We put forth Our signs in diverse forms, and yet they turn away from them. 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 [Our] message-bearers only as heralds of glad tidings and as warners: hence, all who believe and live righteously - no fear need they have, and neither shall they grieve; 48 Those who reject Our revelations will certainly be punished for their evil deeds. 49 Say [O Prophet]: "I do not say unto you, 'God's treasures are with me,'; nor [do I say,] 'I know the things that are beyond the reach of human perception'; nor do I say unto you, 'Behold, I am an angel': I but follow what is revealed to me." Say: "Can the blind and the seeing be deemed equal? Will you not, then, take thought?" 50
