وحدثنا أبي - رضي الله عنه - قال: حدثنا سعد بن عبد الله، قال: حدثنا أحمد بن محمد بن عيسى، عن الحسن بن علي بن فضال، عن علي بن أبي حمزة، عن أبي بصير قال: قلت لأبي عبد الله عليه السلام: من آل محمد صلى الله عليه وآله؟ قال: ذريته. فقلت: أهل بيته؟ قال: الأئمة الأوصياء. فقلت: من عترته؟ قال: أصحاب العباء. فقلت: من أمته؟ قال: المؤمنون الذين صدقوا بما جاء به من عند الله عز وجل، المتمسكون بالثقلين اللذين أمروا بالتمسك بهما: كتاب الله عز وجل، وعترته أهل بيته الذين أذهب الله عنهم الرجس وطهرهم تطهيرا. وهما الخليفتان على الأمة بعده عليه السلام.
3.	We were told by my father, may Allah be pleased with him, that he said: We were told by Sa’d bin Abdullah, that he said: We were told by Ahmad bin Muhammed bin Isa, from Hasan bin Ali bin Faddal, from Ali bin Abi Hamza, from Abu Baseer, that he said: I said to Abu Abdillah, peace be upon him: Who are the Aal of Muhammed, Allah’s blessings be upon him and his Family? He said: His offspring. Then I said: His Household? He said: The Succeeding Imams. Then I said: Then who are his ‘Itra’? He said: The people of the Cloak. Then I said: Who are his nation ? He said: The believers who believed in what he brought from Allah, Exalted and Glorious is He, who adhere to the Two Weighty Things whom they were ordered adherence to: the Book of Allah, Exalted and Glorious is He, and his ‘Itra, his Household, from whom Allah has removed all impurity and purified a (complete) purification. They are the Two Successors over the nation  after him, peace be upon him.
