Musnad Abu Ya'la al-Mawsili 148:45

Ishaq ibn Abi Isra'il narrated to us, Ja'far ibn Sulayman narrated to us, Shubayl ibn 'Azrah narrated to us, he said: I and Qatadah entered upon Anas ibn Malik, and Anas ibn Malik narrated to us, he said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The likeness of the righteous companion is like the perfume seller; if you do not receive from him, you receive from his scent. And the likeness of the evil companion is like the blacksmith; if you do not receive from him, you receive from his smoke."
