It is narrated from Sayyiduna Hudhayfah bin al-Yaman (may Allah be pleased with him) that a man from among the Muslims came to the Messenger of Allah (peace and blessings be upon him) and said: "O Messenger of Allah, I have bought a slave; how should I treat him?" He (peace and blessings be upon him) said: "He is your brother in Islam. Burden him with work only as much as he is able to bear, feed him from your own food and clothe him from your own clothing. Then, if you dislike him, sell him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hallam except Sa'id, and it is not narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) except with this chain."
