Everything in this book that is narrated from Abu Wallad Al-Hannat has been transmitted by me from my father - may Allah (swt) be pleased with him - from Sa'd ibn Abdullah, from Al-Haytham ibn Abi Masruq Al-Nahdi, from Al-Hasan ibn Mahbub, from Abu Wallad Al-Hannat, whose name was Hafs ibn Salim, a freed servant (mawla) of Banu Makhzum.
