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)

عَنْ رَسُولِ اللهِ ﷺ قَالَ «مَنْ جَهَّزَ غَازِيًا فِي سَبِيلِ اللهِ فَقَدْ غَزَا وَمَنْ خَلَفَهُ فِي أَهْلِهِ بِخَيْرٍ فَقَدْ غَزَا»
