Abu Musa al-Ash’ari reported that the Prophet, may Allah bless him and grant him peace, said, “The metaphor of the good companion and the bad companion is that of someone with musk and the bellows of the blacksmith. The person with musk either gives it to you, or you buy it or smell its scent while the bellows of the blacksmith burn your body or your clothes or you get from it a foul smell.” [Agreed upon]
