Muhammad b. Abu Bakr b. Hazm said he often heard his father tell that ‘Umar b. al-Khattab used to say, “It is astonishing that one may inherit from a paternal aunt but that she does not inherit.”
‘Abdallah b. ‘Umar reported God’s Messenger as saying, “An estate which was divided in the pre-Islamic period following the division in force then, but any estate in Islamic times must follow the division appointed by Islam.”
‘Umar said, “Learn the rules of inheritance,” Ibn Mas'ud adding, “of divorce and of the pilgrimage,” and both saying, “for it pertains to your religion.”
‘Amr b. Shu'aib, on his father’s authority, said that his grandfather reported the Prophet as saying, ‘‘He who has the right to inherit property inherits the property of an emancipated slave.”
Tirmidhi transmitted it, saying that this is a tradition whose isnad is not strong.
