It was narrated that Tariq bin Shihab said: I saw `Ali (رضي الله عنه) saying on the minbar. By Allah, we have no book we read to you except the Book of Allah, may He be exalted, and this document - which was attached to his sword - that I took from the Messenger of Allah (ﷺ), in which are the rates of zakah. It was attached to a sword that had iron adornments, or he said, that had iron rings.
