عَنْ جُنْدُبِ بْنِ سُفْيَانَ، أَنَّ رَسُولَ الله صلّى الله عليه وسلم كَانَ فِي بَعْضِ الْمَشَاهِدِ وَقَدْ دَمِيَتْ إِصْبَعُهُ، فَقَالَ: هَلْ أَنْتِ إِلاَّ إِصْبَعٌ دَمِيتِ، وَفِي سَبِيلِ الله مَا لَقِيتِ
Hazrat Jundab ibn Sufyanra reported that during one of the battles, the Prophet’ssa finger was wounded and bled. Thus, he said, “You are but a finger that has bled, and what you have encountered, is in the cause of Allah.”
