Ali bin al-Hasan reports from his grandmother that Sayyiduna Imam Hasan bin Ali (may Allah be pleased with him) used to practise 'azl with her (the narrator says:) and that woman was the slave girl of Sayyiduna Imam Hasan (may Allah be pleased with him).
Al-Tabarani recorded it. As for the narrator Ali and his grandmother, I do not know either of them.
