Buraida said that a man of Khuza'a died and his estate was brought to the Prophet who gave instructions to look for an heir of his or some relative, but they found neither, so God’s Messenger said, “Give it to the leading man* of Khuza'a’ (al-kubr. This may mean the greatest in rank or in age, or, more probably, the nearest in kin to the man's oldest ancestor, the one with fewest intermediate links.
Abu Dawud transmitted it. In a version by him he said, “Look for the greatest (akbar. This might mean greatest or oldest, but it is most probably used here in the same sense as al-kubr) man of Khuza'a.'’
‘A’isha said that a client of God’s Messenger died leaving some property, but no relative or child, and God’s Messenger said, “Give what he has left to a man belonging to his village."
You recite this verse, “After a legacy you bequeathe or a debt (Al-Qur’an 4:12),’’ but God’s Messenger decided that a debt should be discharged before a legacy and that the sons of the same mother inherit from one another, but not the sons of one father by different mothers. A man inherits from his brother who has the same father and mother, but not from his brother who has the same father but a different mother.
Tirmidhi and Ibn Majah transmitted it. In a version by Darimi he said, “Brothers who have the same mother inherit from one another but not sons of the same father but of different mothers, etc."
‘Amr b. Shu'aib, on his father's authority, said his grandfather reported the Prophet as saying, “If a man commits fornication with a freewoman or a slave woman the child is the product of fornication, and neither does he inherit nor may anyone inherit from him."
