Everything in this book that is narrated from Jabir ibn Yazid Al-Ju'fi has been transmitted by me from Muhammad ibn Ali Majilawayh - may Allah (swt) be pleased with him - from his uncle Muhammad ibn Abi Al-Qasim, from Ahmad ibn Muhammad ibn Khalid Al-Barqi, from his father, from Amr ibn Shimr, from Jabir ibn Yazid Al-Ju'fi.
