Chapter 24: Chapters on Shares of Inheritance
It was
narrated that ‘Ali bin Abu Talib said: “The Messenger of Allah
(ﷺ) ruled that the sons from the same mother inherit from one
another, but not sons from different mothers. A man inherits from his
full brother from the same father and mother, but not his brothers
from his father.”
Sunan Ibn Majah 2739
