The Book Pertaining to the Merits of the Companions (Allah Be Pleased With Them) of the Holy Prophet (May Peace Be Upon Him) (Kitab Al-Fada'il Al-Sahabah)
Muslim :: Book 31 : Hadith 6175
Abu Barza reported that Allah's Messenger (may peace be upon him) sent a person to a tribe amongst the tribes of Arabia. They reviled him and beat him. He came to Allah's Messenger (may peace be upon him) and narrated to him (the story of atrocities perpetrated upon him by the people of the tribe). Thereupon he (the Holy Prophet) said: If you were to come to the people of 'Uman, they would have neither reviled you nor beaten you.
