Before you We sent forth to other nations, and then seized them with misery and hardship so that they might humble themselves. 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 So when they forgot the advices made to them, We opened the gates of all things for them; to the extent that when they were rejoicing for what they had received, We seized them suddenly, hence they remained dejected. 44 So of the people who did wrong the last remnant was cut off. Praise be to Allah, Lord of the Worlds! 45 Say, "If God should take away your hearing and your sight and seal your hearts, who is the deity who could restore it to you save God?" See how We explain the signs to them in diverse ways, yet they turn away. 46 Say: 'If the chastisement of Allah were to overtake you unawares or openly shall any except the wrong-doing people be destroyed?' 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 And (as for) those who reject Our communications, chastisement shall afflict them because they transgressed. 49 (Muhammad), tell them, "I do not claim to have all the treasures of God in my hands, nor to know the unseen, nor do I claim to be an angel. I follow only what is revealed to me (from God)." Say to them, "Are the blind and the seeing equal?" Why then do you not think? 50
