Indeed We sent to nations before thee, and We seized them with misery and hardship that haply they might be humble; 42 if only, when Our might came upon them, they had been humble! But their hearts were hard, and Satan decked out fair to them what they were doing. 43 When they forgot (all) the advice that they had received, We granted them all means of happiness but they were left in despair when We suddenly took Our bounties back from them. 44 So the roots of the people who were unjust were cut off; and all praise is due to Allah, the Lord of the worlds. 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: "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 do not send apostles but to give good tidings and to warn. Then those who believe or reform will have neither fear nor regret. 48 And those who belie Our signs - torment shall touch them for they have been transgressing. 49 Say, "I do not say to you that I possess the treasures of God, nor do I know the unseen, nor do I say to you that I am an angel. I follow only that which is revealed to me." Say, "Are the blind and the seeing alike? Can you not then think?" 50
