Everything in this book that is narrated from Al-Hasan ibn Ali Al-Kufi has been transmitted by me from my father - may Allah سبحانه وتعالى have mercy on him - from Ali ibn Al-Hasan ibn Ali Al-Kufi, from his father. I have also narrated it from Ja'far ibn Ali ibn Al-Hasan Al-Kufi, from his grandfather Al-Hasan ibn Ali Al-Kufi.
