Chapter 78: Good Manners and Form (Al-Adab)
Narrated Abu Huraira: Allah' s Messenger (ﷺ) said, "Anybody who believes in Allah and the Last Day should not harm his neighbor,
and anybody who believes in Allah and the Last Day should entertain his guest generously and
anybody who believes in Allah and the Last Day should talk what is good or keep quiet. (i. e. abstain
from all kinds of evil and dirty talk).
