Riyah bin Harith says that a group came to Hazrat Ali (may Allah be pleased with him) at "Rahbah" and said, "Peace be upon you, O our master." Hazrat Ali (may Allah be pleased with him) replied, "How can I be your master while you are an Arab people?" They said, "We heard the Prophet (peace and blessings be upon him) say at the place of Ghadir Khumm: 'Whoever's master I am, Ali is also his master.'" When those people left, I also followed them and asked, "Who are these people?" The people told me that they were some Ansari men, among whom was Hazrat Abu Ayyub Ansari (may Allah be pleased with him).
