My uncle passed away, and he owed his wife four thousand dinars as deferred mahr. I accepted it and waived all her rights. Are they absolved of the debt?

Question:
As I informed you in a previous question, my uncle passed away in a car accident, leaving behind a wife and children. The wife was left with a portion of the inheritance and the deferred mahr. I accepted three thousand dinars, whereas the amount determined was four thousand dinars, and I waived all her rights. Given the situation as described, are we absolved of the debt? May Allah reward you with good. This depends on

Answer:
the woman's condition. If she is of sound mind and mature, and she reached a settlement with you for a certain amount of money and waived the remainder, then the settlement is permissible among Muslims, as the Prophet (peace and blessings be upon him) said: If she is not mature, if she is of limited understanding, or if she is not mature in some respects, then this settlement is invalid. Yes.
