Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "The servant is your brother, so when he prepares food for you, have him sit with you (so that he may also eat); if he refuses, then give him food, and do not strike them on their faces."
