Is there sadness and regret in Paradise?

Question:
I ask Allah for you. Your Eminence, the father, the questioner says: If there is no sadness or regret in Paradise, and that it is not devoid of... If there is no sadness or regret in Paradise, and that no regret enters the heart of the one who has fallen short, then what is the distinction of the prophets, the scholars, and the righteous?

Answer:
What enters the heart of the one who has fallen short? Does something, something of regret for his sins enter his heart, or what? No, nothing of regret enters his heart that he sees someone in a better station than him. As for sins, no one enters Paradise with a sin; no one enters Paradise with sins until he is purified from the sins. Even if he had major sins other than shirk (associating partners with Allah), he will be punished by the Fire until he is purified, then he enters Paradise. So he has no sin upon him, because Paradise is the abode of the pure, and none enters it except the pure. It is the abode of the pure, so no one enters it with sins, or falling short, or anything in his heart. Yes, rather, they do not envy one another in their stations.
Just as they are in this world, everyone is satisfied with his station and does not see that anyone is better than him.
