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