(57) باب فَضْلِ أَهْلِ عُمَانَ
Abu Barza reported that Allah's Messenger (ﷺ) sent a person to a tribe amongst the tribes of Arabia. They reviled him and beat him. He came to Allah's Messenger (ﷺ) 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.
