و ما كان فيه عن إسماعيل بن عيسى فقد رويته عن محمّد بن موسى بن المتوكّل- رضي اللّه عنه- قال: حدّثنا عليّ بن إبراهيم، عن أبيه، عن إسماعيل بن عيسى.
Everything in this book that is narrated from Isma'il ibn 'Isa has been transmitted by me from Muhammad ibn Musa ibn Al-Mutawakkil - may Allah (swt) be pleased with him - who said: Ali ibn Ibrahim narrated to us from his father, from Isma'il ibn 'Isa.
