Arabic

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 ‏"‏‏.‏
