Everything in this book that is narrated from Yahya ibn Abbad Al-Makki has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil - may Allah (swt) be pleased with him - from Muhammad ibn Abi Abdullah Al-Asadi Al-Kufi, from Musa ibn Imran Al-Nakha'i, from his uncle Al-Husayn ibn Yazid, from Yahya ibn Abbad Al-Makki.
