It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) concerning the saying of Allah Almighty: "Allah only intends to remove impurity from you, O people of the household" that he said: "This verse was revealed concerning five persons: the Messenger of Allah (peace and blessings be upon him), Sayyiduna Ali (may Allah be pleased with him), Sayyidah Fatimah (may Allah be pleased with her), Sayyiduna al-Hasan (may Allah be pleased with him) and Sayyiduna al-Husayn (may Allah be pleased with him)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Sufyan al-Thawri (may Allah have mercy on him) except Ammar bin Muhammad (may Allah have mercy on him), and no one narrated it from Ammar bin Muhammad (may Allah have mercy on him) except Abu al-Rabi' al-Zahrani (may Allah have mercy on him) and Sulayman al-Shadhakuni (may Allah have mercy on him)."
