Zaid bin Khalid (May Allah be pleased with him) reported:
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].

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)‏‏)‏
