Arabic hadith text
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنِ الأَسْوَدِ بْنِ قَيْسٍ، سَمِعْتُ جُنْدَبًا، يَقُولُ بَيْنَمَا النَّبِيُّ صلى الله عليه وسلم يَمْشِي إِذْ أَصَابَهُ حَجَرٌ فَعَثَرَ فَدَمِيَتْ إِصْبَعُهُ فَقَالَ " هَلْ أَنْتِ إِلاَّ إِصْبَعٌ دَمِيتِ وَفِي سَبِيلِ اللَّهِ مَا لَقِيتِ ".
Translation
Jundab reported that while the Prophet was walking, a stone struck him, he stumbled, and his finger bled. He said: “You are only a finger that has bled; whatever has happened to you is in the cause of Allah.”
