And We did indeed send Messengers to other nations before you and then We seized those nations with misfortune and hardship so that they might humble themselves (before Us). 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 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: Have ye imagined, if Allah should take away your hearing and your sight and seal your hearts, Who is the Allah Who could restore it to you save Allah? See how We display the revelations unto them! Yet still they turn away. 46 Say: "Think ye, if the punishment of Allah comes to you, whether suddenly or openly, will any be destroyed except those who do wrong? 47 And We send not the sent ones except as bearers of glad tidings and warners. Then whosoever believeth and amendeth, on such shall come no fear nor they shall grieve. 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
