[3:188] Those who boast about their works, and wish to be praised for something they have not really done, should not think that they can evade the retribution. They have incurred a painful retribution.
[3:189] To GOD belongs the sovereignty of the heavens and the earth. GOD is Omnipotent.
God is the one who gave them the wealth and intellect, yet they think that they got this all themselves.
[6:46] Say, “What if GOD took away your hearing and your eyesight, and sealed your minds; which god, other than GOD, can restore these for you?” Note how we explain the revelations, and note how they still deviate!
[16:78] GOD brought you out of your mothers’ bellies knowing nothing, and He gave you the hearing, the eyesight, and the brains, that you may be appreciative.
[4:49] Have you noted those who exalt themselves? Instead, GOD is the One who exalts whomever He wills, without the least injustice.
This is also like people at work who try to take the credit of others i.e. opportunist. God exalts whomever He wills. It is like someone who runs in the front of a parade and acts like they are the ones who orchestrated everything. Politicians are infamous for this kind of behavior.
[35:10] Anyone seeking dignity should know that to GOD belongs all dignity. To Him ascends the good words, and He exalts the righteous works. As for those who scheme evil works, they incur severe retribution; the scheming of such people is destined to fail.
From the description that people like this have incurred a painful retribution it tells me that these kind of people are miserable.
For the Disbelievers: Miserable Life Unavoidable
[20:124] “As for the one who disregards My message, he will have a miserable life, and we resurrect him, on the Day of Resurrection, blind.”
