Why does the mother refuse to speak with her son despite his sacrifices for his siblings and his refusal to divide his money with his brother?

If the workshop belongs to the deceased father, it is a right for all heirs according to their legal shares, and no one is permitted to benefit from it without the consent of the others. If the mother asks her son to divide his money with his brother, he is not obligated to obey her in this matter, and her anger at that time would be without justification. He should treat her kindly and well, and if he is able to give his brother some of his money without harming himself, then he should do so, seeking the reward for maintaining kinship ties and honoring his mother.
