"We camped with the Messenger of Allah ﷺ at a place, and the people began passing by. The Messenger of Allah ﷺ would say: 'Who is this, O Abu Hurairah?' So I would say: 'So-and-so.' So he would say: 'What an excellent slave of Allah this is.' And he would say: 'Who is this?' So I would say: 'So-and-so.' So he would say: 'What a bad slave of Allah this is.' Until Khalid bin Al-Walid passed, so he said: 'Who is this?' So I said: 'This is Khalid bin Al-Walid.' He said: 'What an excellent slave of Allah is Khalid bin Al-Walid, a sword from among the swords of Allah.'"  

نَزَلْنَا مَعَ رَسُولِ اللَّهِ ﷺ مَنْزِلاً فَجَعَلَ النَّاسُ يَمُرُّونَ فَيَقُولُ رَسُولُ اللَّهِ ﷺ مَنْ هَذَا يَا أَبَا هُرَيْرَةَ فَأَقُولُ فُلاَنٌ فَيَقُولُ نِعْمَ عَبْدُ اللَّهِ هَذَا وَيَقُولُ مَنْ هَذَا فَأَقُولُ فُلاَنٌ فَيَقُولُ بِئْسَ عَبْدُ اللَّهِ هَذَا حَتَّى مَرَّ خَالِدُ بْنُ الْوَلِيدِ فَقَالَ مَنْ هَذَا فَقُلْتُ هَذَا خَالِدُ بْنُ الْوَلِيدِ فَقَالَ نِعْمَ عَبْدُ اللَّهِ خَالِدُ بْنُ الْوَلِيدِ سَيْفٌ مِنْ سُيُوفِ اللَّهِ
