And assuredly We sent apostles unto communities before thee; then We laid hold of them with adversity and distress, that haply they may 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 people that committed wrong were eliminated. And praise to Allah, Lord of the worlds. 45 Say thou: look ye were Allah to take away your hearing and your sight and seal up your hearts, what god, other than Allah, shall bring them unto you? Behold! how variously We propound the signs, yet they turn aside. 46 Say: Can ye see yourselves, if the punishment of Allah come upon you unawares or openly? Would any perish save wrongdoing folk? 47 We do not send the Envoys, except good tidings to bear, and warning; whoever believes and makes amends -- no fear shall be on them, neither shall they sorrow. 48 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 49 Say, [O Muhammad], "I do not tell you that I have the depositories [containing the provision] of Allah or that I know the unseen, nor do I tell you that I am an angel. I only follow what is revealed to me." Say, "Is the blind equivalent to the seeing? Then will you not give thought?" 50
