It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Indeed, the Magians of this ummah are those who deny the decrees of Allah. If they fall ill, do not visit them; if you meet them, do not greet them with salam; and if they die, do not attend their funerals."
No one narrated this hadith from Imam al-Awza'i (may Allah have mercy on him) other than Baqiyyah (may Allah have mercy on him), and Muhammad bin Musaffa (may Allah have mercy on him) is alone in narrating it.
