Sayyidina Abu Hurayrah narrated: In a journey with Allah’s Messenger ﷺ we halted at a place. People began to go past us. Allah’s Messenger asked, “Who is he, O Abu Hurayrah?” As I named him, he said, “Excellent slave of Allah, this!” Then he asked, “And who is this?” I named him and he said, “Evil slave of Allah, this” So, on, till Khalid ibn Walid passed by and he asked, “Who is he?” I named him, “Khalid ibn Walid.” He said, “Excellent slave of Allah, Khalid ibn Walid, a sword of the swords of Allah!” [Ahmed 8728]
