In one of the holy Battles a finger of Messenger of Allah ﷺ (got wounded and) bled. He said, "You are just a finger that bled, and what you got is in Allah's Cause."
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ فِي بَعْضِ الْمَشَاهِدِ وَقَدْ دَمِيَتْ إِصْبَعُهُ فَقَالَ هَلْ أَنْتِ إِلاَّ إِصْبَعٌ دَمِيتِ وَفِي سَبِيلِ اللَّهِ مَا لَقِيتِ
