Everything in this book that is narrated from Yaqub ibn Shuayb has been transmitted by me from Muhammad ibn Al-Hasan - may Allah (swt) be pleased with him - from Al-Hasan ibn Matil, from Muhammad ibn Al-Husayn ibn Abi Al-Khattab, from Jafar ibn Bashir, from Hammad ibn Uthman, from Yaqub ibn Shuayb ibn Maytham Al-Asadi, who was a freed servant (mawla) and a Kufan.
