Abu al-Bakhtari narrates from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "My Companions are one group, and the rest of the people are another group." At that, Zayd bin Thabit and Rafi' bin Khadij (may Allah be pleased with them both) said: He has spoken the truth.
