Sacrifice in Allah’s cause

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 Sufyan^ra reported that during one of the battles, the Prophet’s^sa 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.”
