Sayyiduna Zayd bin Arqam (may Allah be pleased with him) narrates: Sayyiduna Ali (may Allah be pleased with him) called on the people to bear witness. He said: "I ask, by Allah, the man who heard the Prophet (peace and blessings be upon him) say: 'O Allah, whoever I am the mawla of, Ali is also his mawla. O Allah, befriend whoever befriends him, and be hostile to whoever is hostile to him.'" The narrator says: Sixteen men stood up and bore witness to it.
Ahmad recorded it. Its chain contains Abu Sulayman, whom I do not know, unless he is Bashir bin Salman; if it is he, then he is thiqah (trustworthy). The rest of its narrators are thiqat (trustworthy).
