What is my sister entitled to from the estate of our mother, who passed away five years ago, especially concerning the gold that was in her possession? And should the costs of treatment, hospitalization, charity, and travel that the speaker undertook for her mother be divided?

The reward for honoring one's parents is great, and a daughter's spending on her poor mother is obligatory, and she is not permitted to reclaim what she spent from the inheritance. As for the disobedient sister, she is not deprived of her lawful inheritance, and her share is communal in the entire estate unless the heirs agree otherwise. The mother's bequest to allocate something to her daughter has no validity. The division of the mother's expenses among the children should be according to their financial capacity, and the daughter may demand her sister's share of the expenses if she intends to claim it back from her.
