Everything in this book that is narrated from Abd Al-Karim ibn Amr has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah سبحانه وتعالى be pleased with them both - from Sad ibn Abdullah, from Ahmad ibn Muhammad ibn Isa, from Ahmad ibn Muhammad ibn Abi Nasr Al-Bazanti, from Abd Al-Karim ibn Amr Al-Khathami, whose title was Karram.
