My father divided what he owned among his sons before his death, excluding his daughters. Was he sinful, and is it sufficient for the daughters to forgive their father?

Question:
My father has passed away. Before his death, he divided the lawful wealth he possessed among his five sons. The division was the result of a discussion among these brothers regarding the money, as some of them were unmarried. The father’s intention was to settle the dispute among them, but he gave nothing to his two daughters. It is worth noting that he had kept a portion of the money for himself during his lifetime. After his death (may Allah have mercy on him), the brothers divided the remaining money among the two sisters, the mother, and the children, and they did not take anything else from him. The question is: Was my father sinful toward my sisters? And if so, and the daughters have asked Allah to forgive their father, is the daughters’ forgiveness sufficient? May Allah reward you with good.

Answer:
The Prophet (peace and blessings be upon him) prohibited giving a gift to some children while withholding it from others. Therefore, it is not permissible to give to the males and deprive the females. Rather, it is obligatory to be just among one’s children. He (peace and blessings be upon him) said: So what this father did was a great error, and he is sinful because of it. As for the fact that the daughters forgave him afterward, that is good, and they have been kind to their father. We hope that Allah will forgive him if they have forgiven him for their right. Yes.
