Clarification of the Transmission Chain to Al-Husayn Ibn Hammad

Everything in this book that is narrated from Al-Husayn ibn Hammad has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah سبحانه وتعالى be pleased with them both - from Sa'd ibn Abdullah and Al-Himyari together, from Ahmad ibn Muhammad ibn 'Isa, from Al-Bazanti, from Abdul Karim ibn 'Amr, from Al-Husayn ibn Hammad Al-Kufi.
