In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
“When the servant of any one of you brings his food to him, if he does not make him sit with him to eat, then let him give him a morsel [or a mouthful], for he has endured its heat and preparation”.
Shaikh Zayd Bin Haadi [Rahimahullaah] said: This hadeeth has preceded [i.e. Vol 1. Page 50] in a similar wording. We did explain it and mention what was easy for us to derive of its beneficial points.
This deed is proof of [one’s] good manners, for indeed good manners is practised when [dealing] with everyone. The servant who delivers a service in the house by preparing food, serving drinks and so on, it is obligatory to be kind towards him, comfort him and give his service importance. So, when he brings food to the owner of the house and has endured hardship in that, he [i.e. the owner of the house] should make him sit with him, for this will not increase a person in anything else except a higher status [in the sight of Allaah]. And if he does not make the servant sit with him, then let him give him what is easy for him to give, for indeed the servant is in need of it as long as he is in the presence of the owner of the house. If he does so, then indeed he has acquired his share of good manners. In summary, good manners includes mercy, selflessness and kind treatment as seen in this hadeeth.
