Will a believer remain in Paradise with his [original] form and personality, so that he loves those whom he loved in this world, or will his personality and characteristics change?

A Muslim must seek beneficial knowledge that brings him closer to Paradise, and avoid questions that do not lead to action. The people of Paradise will be cleansed of bad morals, as Allah Almighty said: "And We will remove whatever is in their breasts of resentment; 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.'" The people of Paradise are loving towards each other, and there is no mutual hatred among them; their hearts are as one man's heart.
