Chapter 43: General Behavior (Kitab Al-Adab)
Abu Bakrah said that when a man praised another man in his face in the presence of the Prophet (ﷺ) said: You have beheaded your friend (saying it three times). He then said: One who cannot help expressing praise of his companion, should say: I consider him such and such (as he intends to say), but I do not declare him pure with Allah.
