Musnad Ahmad 788:16

'Abd al-Razzaq narrated to us, Sufyan informed us, from Layth, from Abu Burdah, from Abu Musa, from the Prophet, peace and blessings of Allah be upon him, who said: "If you pass by with arrows in the markets of the Muslims or in their mosques, then hold them by the blades so that you do not wound anyone with them."
