Clarification of the Transmission Chain to Mamar Ibn Khallad

Everything in this book that is narrated from Mamar ibn Khallad has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil, Muhammad ibn Ali Majilawayh, and Ahmad ibn Ziyad ibn Jafar Al-Hamadani - may Allah (swt) be pleased with them all - from Ali ibn Ibrahim ibn Hashim, from his father, from Mamar ibn Khallad.
