Everything in this book that is narrated from Al-Mualla ibn Khunays has been transmitted by me from my father - may Allah سبحانه وتعالى have mercy on him - from Sad ibn Abdullah, from Ahmad ibn Muhammad ibn Isa, from Abd Al-Rahman ibn Abi Najran, from Hammad ibn Isa, from Al-Masmai, from Al-Mualla ibn Khunays. He was a freed servant (mawla) of Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, a Kufan, and a cloth seller (bazzaz). He was killed by Dawud ibn 'Ali.
