Zaid bin Khalid al Juhani reported that Apostle of Allaah ﷺ as saying “He who equips a fighter in Allaah’s path has taken part in the fighting. And he looks after a fighter’s family when he is away has taken part in the fighting.” (Using translation from Abū Dāʾūd 2509)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ جَهَّزَ غَازِيًا فَقَدْ غَزَا وَمَنْ خَلَفَهُ بِخَيْرٍ فَقَدْ غَزَا»
