Is it permissible for a wife to accept money from her husband, knowing that it was acquired through the forbidden sport of boxing, given that it is a debt owed to her and she needs the money for the expenses of Hajj?

It was previously explained that boxing is impermissible, so the wife should advise her husband to abandon it and repent to Allah. As for the wife reclaiming her dowry from her husband's earnings acquired through boxing, it is permissible according to the most authoritative scholarly opinions.
