Clarification of the Transmission Chain to Sahl Ibn Al-yasa'

Everything in this book that is narrated from Sahl ibn Al-Yasa' has been transmitted by me from Ahmad ibn Ziyad ibn Ja'far Al-Hamadani - may Allah سبحانه وتعالى be pleased with him - from Ali ibn Ibrahim, from his father, from Sahl ibn Al-Yasa'.
