´Jabir narrated :` "The Messenger of Allah(s.a.w) prohibited passing an unsheathed sword."
Shaykh Dr. Abdur Rahman Freywai
Explanation: 1: This prohibition is due to the fact that, at times, the person holding the unsheathed sword may himself get injured, and there is also a risk of causing harm to others with it.
