No one is wounded in the way of Allah except that he comes on the Day of Judgment with his wound bleeding; the color is that of blood, and the smell is that of musk.

The Prophet (may Allah's peace and blessings be upon him) speaks of the merit of Jihad in Allah's cause and of the good reward that one receives by taking part in it. If one is wounded in Allah's cause, then gets killed or recovers, he will come on the Day of Judgment with a sign of his Jihad and sacrifice. His wound will be fresh; it will have the color of blood and the scent of musk.
