Everything in this book that is narrated from Abd Al-Azim ibn Abdullah Al-Hasani has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil - may Allah سبحانه وتعالى be pleased with him - from Ali ibn Al-Husayn Al-Sadabadi, from Ahmad ibn Abi Abdullah Al-Barqi, from Abd Al-Azim ibn Abdullah Al-Hasani, who was regarded as trustworthy and praiseworthy (mardiyyan). I have also narrated it from Ali ibn Ahmad ibn Musa - may Allah سبحانه وتعالى have mercy on him - from Muhammad ibn Abi Abdullah Al-Kufi, from Sahl ibn Ziyad Al-Adami, from Abd Al-Azim.
