8. It is narrated from the narrator of the previous Hadith from Muhammad ibn Ali from Ali ibn Hammad from Hariz from certain persons of his people who has narrated the following: “Abu ‘Abd Allah (a.s.), has said, ‘Taking an oath sinfully is that which subjects one to the fire whereby a man holds back the right of a Muslim by seizing his assets.”’
