حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَخْبَرَنَا إِسْمَاعِيلُ، رَأَيْتُ بِيَدِ ابْنِ أَبِي أَوْفَى ضَرْبَةً، قَالَ ضُرِبْتُهَا مَعَ النَّبِيِّ صلى الله عليه وسلم يَوْمَ حُنَيْنٍ‏.‏ قُلْتُ شَهِدْتَ حُنَيْنًا قَالَ قَبْلَ ذَلِكَ‏.‏

Narrated Isma`il: I saw (a healed scar of) blow over the hand of Ibn Abi `Aufa who said, "I received that blow in the battle of Hunain in the company of the Prophet." I said, "Did you take part in the battle of Hunain?" He replied, "Yes (and in other battles) before it." Translation Not Available
