Yahya related to me from Malik from Abu'z-Zinad from al-Araj from
Abu Hurayra that the Messenger of Allah, may Allah bless him and grant
him peace, said, "By He in whose hand my self is! None of you is
wounded in the way of Allah - and Allah knows best who is wounded in
HisWay, but that when the Day of Rising comes, blood will gush forth
from his wound. It will be the colour of blood, but its scent will be
that of musk."
Muwatta Malik Book 21, Hadith 31
