Before thee We sent (messengers) to many nations, and We afflicted the nations with suffering and adversity, that they might learn humility. 42 But when misfortune befell them from Us why did they not humble themselves? Their hearts had hardened and Satan had made their deeds seem fair to them. 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 did wrong were cut off. And all the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinns, and all that exists). 45 Say: "Think ye, if Allah took away your hearing and your sight, and sealed up your hearts, who - a god other than Allah - could restore them to you?" See how We explain the signs by various (symbols); yet they turn aside. 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 send forth Our Messengers only to give glad tidings to mankind and to warn them. Those who believe and mend their ways shall have nothing to fear or to be saddened. 48 Chastisement will befall those who reject Our signs because of their disobedience. 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
