Hadith 6257
وَعَن أبي عُبَيدةَ أَنَّهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «خَالِدٌ سَيْفٌ مِنْ سُيُوفِ اللَّهِ عَزَّ وَجَلَّ وَنِعْمَ فَتَى الْعَشِيرَةِ» . رَوَاهُمَا أَحْمد
Abu `Ubaida told that he heard God's messenger say, "Khalid is one of the swords of God who is great and glorious, and he is the fine warrior of the tribe." Ahmad transmitted the two traditions.
