The Prophet ﷺ said, "When your servant brings your food to you, if you do not ask him to join you, then at least ask him to take one or two handfuls, for he has suffered from its heat (while cooking it) and has taken pains to cook it nicely." (Using translation from Bukhārī 5460)
"إذ أتى أحدَكم خادمُه بطعامِه، قد كفاه علاجَه ودخانَه فليُجلسْه مَعه، فإن لم يجْلِسُه معه فلْينَاولْه أُكلةً أو أكْلتين فإنه ولى حرَّه وعلاجَه".
