(38) باب فَضْلِ إِعَانَةِ الْغَازِي فِي سَبِيلِ اللَّهِ بِمَرْكُوبٍ وَغَيْرِهِ وَخِلاَفَتِهِ فِي أَهْلِهِ بِخَيْرٍ
The above tradition has been narrated on the authority of Khalid al- Juhani who said:
The Prophet of Allah (ﷺ) said: He who equips a warrior in the way of Allah (is like one who dctually fights) aud he who looks after the family of a warrior in the way of Allah in fact participated in the battle.
