Do the people of Paradise enter with the same minds and thoughts after being purified from impurities and disturbances, or do their thoughts and minds transform into another state?

The minds and knowledge of the people of Paradise will not diminish; rather, they will increase in strength, clarity, and perception. Everything that marred them in this world will be removed. Islamic scholars have agreed that the minds of the people of Paradise will increase in clarity and perception. Evidence for this includes their conversations with the people of Hell, their remembrance of their state in this world, and their desire to inform the people of this world about the blessings they have attained, as in the verse: "Oh, would that my people knew for what my Lord has forgiven me and made me among the honored!" [Qur’an 36:26-27]. And it is authentically narrated that those martyrs expressed: "Inform our people that we have met our Lord, and He was pleased with us and made us pleased."

This is further confirmed by the Almighty's saying: "And We will remove whatever is in their breasts of resentment, [as] rivers will flow beneath them; and they will say, 'Praise to Allah, who has guided us to this; and we would not have been guided if Allah had not guided us.'" [Al-A'raf: 43], and His saying: "And We will remove whatever is in their breasts of resentment, [as] brothers, facing each other on couches." [Al-Hijr: 47], and the Prophet's (peace be upon him) description of them: "Their hearts will be as one man's heart; there will be no disagreement among them, nor hatred."
