Everything in this book that is narrated from Muhammad ibn Hakim has been transmitted by me from my father - may Allah سبحانه وتعالى have mercy on him - from Abdullah ibn Jafar Al-Himyari, from Ahmad ibn Abi Abdullah, from his father, from Hammad ibn Isa, from Hariz, from Muhammad ibn Hakim. I have also narrated it from Muhammad ibn Al-Hasan - may Allah سبحانه وتعالى have mercy on him - from Muhammad ibn Al-Hasan Al-Saffar, from Yaqub ibn Yazid, from Muhammad ibn Abi Umayr, from Muhammad ibn Hakim.
