It is narrated from Riyah bin Harith that a group of people came to Sayyiduna Ali (may Allah be pleased with him) at the place of Rahbah and they said: O our master! Peace be upon you. Sayyiduna Ali (may Allah be pleased with him) said: How can I be your master, when you are an Arab people? Those people said: We heard the Messenger of Allah (peace and blessings be upon him) say at the occasion of Ghadir Khumm: "Whoever I am the master of, Ali is also his master." Riyah says: When those people left, I followed them and asked: Who are these people? The people informed me that they are Ansar, and among them was Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him).

(Second chain) Riyah says: I saw a group of Ansar, they came to Sayyiduna Ali (may Allah be pleased with him) at Rahbah. Sayyiduna Ali (may Allah be pleased with him) asked: Who are you people? They said, O Commander of the Faithful! We are your friends, then he mentioned a hadith with the same meaning as mentioned above.
