Abu Dawud Book 12, Hadith Number 2916.
Chapter : Abrogation of inheritance by alliance by the command of inheritance of relationship.
Narated By N/A : Ibn ‘Abbas explaining the Quranic verses: “To those also, to whom your right hand was pledged, give due proportion.” When the Emigrants came to Medina, they inherited from the Helpers without any blood relationship with them for the brotherhood which the Apostle of Allah (PBUH) established between them. When the following verse was revealed: “To (benefit) everyone we have appointed shares and heirs to property left by parents and relatives,” it abrogated the verse: “To those also, to whom your right hand was pledged, give their due portion.” This alliance was made for help, well wishing and cooperation. Now a legacy can be made for him. (The right to) inheritance was abolished.
