Musnad AhmedIt 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.
