Clarification of the Transmission Chain to Al-Mufaddal Ibn Umar

Everything in this book that is narrated from Al-Mufaddal ibn Umar has been transmitted by me from Muhammad ibn Al-Hasan - may Allah (swt) have mercy on him - from Al-Hasan ibn Mattil Al-Daqqaq, from Ahmad ibn Abi Abdullah, from his father, from Muhammad ibn Sinan, from Al-Mufaddal ibn Umar Al-Ju'fi Al-Kufi, who was a freed servant (mawla).
