Sayyiduna Wathilah bin Asqa’ (may Allah be pleased with him) narrates: I inquired about Sayyiduna Ali (may Allah be pleased with him) at his house, and I was informed that he had gone out and would return with the Prophet (peace and blessings of Allah be upon him). Then he came, and the Prophet (peace and blessings of Allah be upon him) entered the house. I also entered. The Prophet (peace and blessings of Allah be upon him) sat on the bedding. He seated Lady Fatimah (may Allah be pleased with her) on his right, Sayyiduna Ali (may Allah be pleased with him) on his left, and Sayyiduna Hasan (may Allah be pleased with him) and Sayyiduna Husayn (may Allah be pleased with him) in front of him. The Prophet (peace and blessings of Allah be upon him) recited (this verse):“O People of the House! Allah only wishes to remove impurity from you and to purify you thoroughly.”Then he said:“O Allah! These are my Ahl al-Bayt (family).”

Sayyiduna Wathilah (may Allah be pleased with him) narrates: He said from the edge of the house,“O Messenger of Allah! Am I also among your Ahl al-Bayt?”The Prophet (peace and blessings of Allah be upon him) said:“You are also among my Ahl al-Bayt.”Sayyiduna Wathilah (may Allah be pleased with him) says: Of all the things I could have hoped for, this was the most remarkable.
