Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 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 So the last remnant of the people who did evil was cut off. Praise belongs to God the Lord of all Being. 45 Say: 'What think you? If God seizes your hearing and sight, and sets a seal upon your hearts, who is a god other than God to give it back to you?' Behold how We turn about the signs! Yet thereafter they are turning away. 46 Say: "Imagine if the punishment of God were to come unawares, or openly, who will perish but the evil-doers?" 47 We do not send Messengers except as bearers of glad tidings and warners. So, he who believes in their message and mends his conduct need have no fear and need not grieve; 48 And those who deny Our signs – the punishment will afflict them for their disobedience. 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
