Everything in this book that is narrated from Hariz ibn Abdullah concerning Zakat has been transmitted by me from Muhammad ibn Al-Hasan - may Allah (swt) be pleased with him - from Muhammad ibn Al-Hasan Al-Saffar, from Al-Abbas ibn Ma'ruf, from Isma'il ibn Sahl, from Hammad ibn Isa, from Hariz ibn Abdullah. I have also narrated it from my father - may Allah (swt) be pleased with him - from Ali ibn Ibrahim, from his father, from Hammad, from Hariz.
