Does the deceased mother inherit from her deceased relative who has no heirs from among his children and wife, and who has living sisters?

If the mother dies before her brother, she does not inherit from him. However, if she dies after him, she inherits, provided the deceased has no father to exclude her, and her share then passes to her heirs after her death. To determine how to divide the maternal uncle's inheritance, you can use the inheritance calculation tool on the "Inheritance" page of the Islamweb website.
