You recite: "after the payment of legacies he may have bequeathed or debts" [an-Nisa" 4:12]. The Messenger of Allah (ﷺ) ruled that debts must be paid before carrying out bequests, [And he ruled] that sons from the same father and mother inherit from one another, but sons from different mothers (but the same father) do not. A man inherits from his brother through his father and mother but not from his brother through his father only.
