Sayyiduna Jabir (may Allah be pleased with him) says: Sayyidah Juwayriyah (may Allah be pleased with her) said to the Prophet (peace and blessings be upon him): "I want to free this slave." The Prophet (peace and blessings be upon him) said: "Give him to your maternal uncle who lives among the Bedouins; he will do his work for him. That will bring you a greater reward."
Al-Bazzar recorded it, and its narrators are the narrators of the Sahih.
