Everything in this book that is narrated from Hafs ibn Al-Bukhtari has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah سبحانه وتعالى be pleased with them both - from Sa'd ibn Abdullah and Abdullah ibn Ja'far Al-Himyari together, from Ya'qub ibn Yazid, from Muhammad ibn Abi 'Umayr, from Hafs ibn Al-Bukhtari Al-Kufi.
