Maʿānī al-ʾAkhbār, no. 116

1. My father, may Allah grant him mercy, said: We were told by Sa’d bin Abdullah, from Muhammed bin Hasan, from Ja’far ibn Basheer, from Hussain bin Abi’l-‘Alaa’, from Abdullah bin Maysara, that he said: I said to Abu Abdillah, peace be upon him: We only say: «O Allah, send Your blessings upon Muhammed and the Family of Muhammed» Some people then say: «We are the Family of Muhammed. Then he said: The Family of Muhammed are only those whom Allah, Exalted and Glorious is He, forbade Muhammed to marry.
