Sayyiduna Zayd bin Khalid al-Juhani رضي الله عنه narrates this statement of the Noble Prophet صلى الله عليه وسلم: "Whoever equips a warrior (mujahid) with supplies, he also receives a reward like that of the warrior. And whoever looks after the family of a warrior in his absence, he also receives a reward like that of the warrior." Ibn Shihab states: Busar bin Sa'id narrated this hadith to me.
