(38) باب غَزْوَةُ خَيْبَرَ
Narrated Ibn `Umar:
On the day of Khaibar, Allah's Messenger (ﷺ) divided (the war booty of Khaibar) with the ratio of two shares for the horse and one-share for the foot soldier. (The sub-narrator, Nafi` explained this, saying, "If a man had a horse, he was given three shares and if he had no horse, then he was given one share.")
