Chapter : He who goes in the mosque or in the bazaar or a place of gathering like it with a weapon should see that the spearhead does not harm anyone.

Jabir reported that Allah’s Messenger (may peace be upon him) commanded a person who had been distributing arrows freely in the mosque that he should not move about in the mosque but by catching hold of their iron-heads. Ibn Rumh narrated this with a slight variation of wording.
