Abu al-Bakhtari (may Allah have mercy on him) narrates from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him), who said: The Prophet (peace and blessings be upon him) said: "The people are one group, and my Companions are a separate group." Sayyiduna Zayd bin Thabit and Sayyiduna Rafi' bin Khadij (may Allah be pleased with them both) said: He has spoken the truth. And they were at that time with Marwan bin al-Hakam.
