Everything in this book that is narrated from Isma'il ibn 'Abd Al-Rahman Al-Ju'fi Al-Kufi 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, from his father, from Muhammad ibn Sinan and Safwan ibn Yahya, from Isma'il ibn 'Abd Al-Rahman Al-Ju'fi Al-Kufi.
