Imam Ja'far al-Sadiq (may Allah have mercy on him) reports this statement of his father: "Between Sayyiduna Hasan (may Allah be pleased with him) and Sayyiduna Husayn (may Allah be pleased with him) there was a gap of only one period of purity (tuhr)."
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih, except that Imam al-Baqir (may Allah have mercy on him) did not live in the time of that event.
