Everything in this book that is narrated from Muhammad ibn Bijil, the brother of Ali ibn Bijil, 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 Ali ibn Al-Hasan ibn Ribaat, from Muhammad ibn Bijil, the brother of Ali ibn Bijil ibn Aqil Al-Kufi.
