Amr bin Shu'ayb narrates from his father, and he from his grandfather (Sayyiduna Abdullah bin Amr, may Allah be pleased with them both), that the Prophet (peace and blessings be upon him) said: "There is no divorce without ownership, nor is there freeing (of a slave)."
(b) In the narration of Ibn Abi Arubah (may Allah have mercy on him): "A man cannot divorce one whom he does not own, cannot sell what is not in his ownership, and cannot free a slave without ownership."
