“The likeness of a righteous friend and an evil friend, is the likeness of a (musk) perfume seller and a blacksmith. As for the perfume seller, he may either bestow something on you, or you may purchase something from him, or you may benefit from his sweet smell. And as for the blacksmith, he may either burn your clothes, or you may be exposed to his awful smell.”
[Bukhari and Muslim]
