Clarification of the Transmission Chain to Durust Ibn Abi Mansur

Everything in this book that is narrated from Durust ibn Abi Mansur has been transmitted by me from my father - may Allah (swt) have mercy on him - from Sad ibn Abdullah, from Ahmad ibn Muhammad ibn Isa, from Al-Hasan ibn Ali Al-Washsha', from Durust ibn Abi Mansur Al-Wasiti.
