Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن زيد بن خالد، رضي الله عنه أن رسول الله صلى الله عليه وسلم قال: "من جهز غازيًا في سبيل الله فقد غزا ومن خلف غازيا في أهله بخير فقد غزا" ((متفق عليه))
The Messenger of Allah (ﷺ) said, "He who equips a Ghazi (fighter) in the way of Allah is as if he has taken part in the fighting himself; and he who looks after the dependants of a Ghazi in his absence, is as if he has taken part in the fighting himself."[Al-Bukhari and Muslim].
