Everything in this book that is narrated from Ibrahim ibn Maymun has been transmitted by me from Muhammad ibn Al-Hasan - may Allah سبحانه وتعالى be pleased with him - from Al-Husayn ibn Al-Hasan ibn Aban, from Al-Husayn ibn Sa'id, from Hammad ibn 'Isa, from Mu'awiyah ibn 'Ammar, from Ibrahim ibn Maymun, the cloth seller from Herat and a freed servant (mawla) of the family of Al-Zubayr.
