A finger of the Messenger of Allah ﷺ was wounded in one of the encounters He said: Thou art just a little finger which has bled, and what thou hast experienced is in the cause of Allah. (Using translation from Muslim 1796a)
دَمِيَتْ إِصْبَعُ رَسُولِ اللهِ ﷺ فَقَالَ هَلْ أَنْتِ إِلَّا إِصْبَعٌ دَمِيتِ وَفِي سَبِيلِ اللهِ مَا لَقِيتِ
