و ما كان فيه عن سعد بن عبد اللّه فقد رويته عن أبي؛ و محمّد بن الحسن- رضي اللّه عنهما- عن سعد بن عبد اللّه بن أبي خلف.
Everything in this book that is narrated from Sa'd ibn Abdullah has been transmitted by me from my father and from Muhammad ibn Al-Hasan - may Allah (swt) be pleased with them both - from Sa'd ibn Abdullah ibn Abi Khalaf.
