Clarification of the Transmission Chain to Abu Al-Mughira Humayd Ibn Al-Muthanna Al-Ajli

Everything in this book that is narrated from Abu Al-Mughira Humayd ibn Al-Muthanna Al-Ajli has been transmitted by me from my father - may Allah سبحانه وتعالى have mercy on him - from Sad ibn Abdullah, from Muhammad ibn Al-Husayn ibn Abi Al-Khaṭṭab, from Uthman ibn Isa, from Abu Al-Mughira Humayd ibn Al-Muthanna Al-Ajli. He was a trustworthy Arab from Kufa and had authored a book.
