“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."
Sahih Al Bukhari Hadith No. 370 Volume No. 007 Book No. 065 Narrated by Abu Huraira (r.a.)
