Clarification of the Transmission Chain to Muhammad Ibn Hurman and Jamil Ibn Darraj

Everything in this book that is narrated from Muhammad ibn Hurman and Jamil ibn Darraj has been transmitted by me from my father - may Allah (swt) be pleased with him - from Sa'd ibn Abdullah, from Ya'qub ibn Yazid, from Muhammad ibn Abi 'Umayr, from Muhammad ibn Hurman and Jamil ibn Darraj.
