And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us]. 42 Why did they not submit themselves (to God) when Our torment struck them. Instead, their hearts were hardened and Satan made their evil deeds seem attractive 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, "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: 'What do you see yourselves then, if the punishment of Allah overtook you suddenly or openly, would any perish but the harmdoing nation' 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 But those who cry lies to Our signs, them the chastisement shall visit, for that they were ungodly. 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
