Mukhtasar Bukhari (Abridged) 1212 — Virtue of one wounded or pierced

It is narrated from Sayyiduna Jundub bin Sufyan, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, was in a battle when his finger became wounded and bloodied. So the Prophet, peace and blessings be upon him, said: "You are but a finger that has become bloodied, and this calamity you have borne is in the way of Allah."
