Sahih al-Bukhari, Volume 5, Book 59, Hadith 565 (USC-MSA) ⓘ
Narrated Khalid bin Al-Walid: On the day of Mu'tah, nine swords were broken in my hand and only a Yemenite sword of mine remained in my hand.
حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ، قَالَ حَدَّثَنِي قَيْسٌ، قَالَ سَمِعْتُ خَالِدَ بْنَ الْوَلِيدِ، يَقُولُ لَقَدْ دُقَّ فِي يَدِي يَوْمَ مُوتَةَ تِسْعَةُ أَسْيَافٍ، وَصَبَرَتْ فِي يَدِي صَفِيحَةٌ لِي يَمَانِيَةٌ.
