Clarification of the Transmission Chain to Muhammad Ibn Abi 'umayr

Everything in this book that is narrated from Muhammad ibn Abi 'Umayr has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah (swt) be pleased with them both - from Sa'd ibn Abdullah and Al-Himyari together, from Ayyub ibn Nuh, Ibrahim ibn Hashim, Ya'qub ibn Yazid, and Muhammad ibn Abdul Jabbar, all from Muhammad ibn Abi 'Umayr.
