It was narrated that Tariq bin Shihab said: I saw ‘Ali (رضي الله عنه) on the minbar, delivering a speech, wearing a sword that had an adornment of iron, and l heard him say: By Allah, we do not have any book that we recite to you except the Book of Allah, may He be exalted, and this document that the Messenger of Allah (ﷺ) gave to me. In it are the rates of zakah. He said: [This was] a document that was attached to his sword.
