Abu Bakr ibn Abi Shaybah narrated to us, Sufyan ibn 'Uyaynah narrated to us, from Burayd ibn 'Abd Allah, from his grandfather, from Abu Musa, from the Prophet, peace and blessings be upon him.
And Muhammad ibn al-'Ala' al-Hamdani narrated to us (and the wording is his), Abu Usamah narrated to us, from Burayd, from Abu Burdah, from Abu Musa, from the Prophet, peace and blessings be upon him, who said:
"The example of the righteous companion and the bad companion is like the carrier of musk and the blower of the bellows. The carrier of musk will either give you some, or you will buy from him, or you will find from him a pleasant fragrance. And the blower of the bellows will either burn your clothes, or you will find from him a foul odor."
