Everything in this book that is narrated from Al-Hasan Al-Sayqal has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil - may Allah (swt) be pleased with him - from Ali ibn Al-Husayn Al-Sadabadi, from Ahmad ibn Abi Abdullah Al-Barqi, from his father, from Yunus ibn Abd Al-Rahman, from Al-Hasan ibn Ziyad Al-Sayqal Al-Kufi, whose kunyah is Abu Al-Walid, and he was a mawla.
