Mishkat al-Masabih 19 Jihad كتاب الجهاد 16

وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا يُكَلَّمُ أَحَدٌ فِي سَبِيلِ اللَّهِ وَاللَّهُ أَعْلَمُ بِمَنْ يُكَلَّمُ فِي سَبِيلِهِ إِلَّا جَاءَ يَوْمَ الْقِيَامَةِ وَجُرْحُهُ يَثْعَبُ دَمًا اللَّوْنُ لَوْنُ الدَّمِ والريحُ ريحُ المسكِ»

Abu Huraira reported God’s Messenger as saying, “No one is wounded in God’s path, and God knows best those who are wounded in His path, without coming on the day of resurrection with his wound spouting blood, the colour being that of blood but the fragrance that of musk.” (Bukhari and Muslim.)
