Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to give a ruling concerning a male or female slave owned jointly by several partners: "If one of them frees his share and he has the wealth, the rest of the slave shall also be freed. A fair value shall be assessed, the other partners shall be paid according to their shares, and the slave's way shall be left free." Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this hadith from the Prophet (peace and blessings be upon him) as the Prophet's own words.
