Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When the servant of any one of you brings his food, since he has endured its heat and (further) toil and hardship (in preparing it), (therefore the master should let him sit with him so that he may also partake of the food). If he does not wish to let him sit with him to eat, then he should give him some of the food."
