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.

نَبِيُّ اللَّهِ ﷺ مَنَ جَهَّزَ غَازِيًا فَقَدْ غَزَا وَمَنْ خَلَفَ غَازِيًا فِي أَهْلِهِ فَقَدْ غَزَا
