Book of Jihad and Military Expeditions
Virtue of one wounded or pierced in Allah’s path.
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."
