Everything in this book that is narrated from Mu'awiyah ibn 'Ammar 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 Al-Himyari together, from Ya'qub ibn Yazid, from Safwan ibn Yahya and Muhammad ibn Abi 'Umayr together, from Mu'awiyah ibn 'Ammar Al-Dahni Al-Ghanawi Al-Kufi, the freed servant (mawla) of Bujaylah, and he was known by the kunya Abu Al-Qasim.
