Musnad Ahmad 937:194

'Abd al-Malik ibn 'Amr narrated to us, Sufyan narrated to us, from Mansur, from Mujahid, from Muwarriq, from Abu Dharr, from the Prophet, peace be upon him, who said: "Whoever among your servants is compatible with you, feed them from what you eat and clothe them from what you wear," or he said: "what you clothe yourselves with." "And whoever is not compatible with you, sell them, and do not torment the creation of Allah."
