Silsilah Sahihah

It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: “Whoever equips a warrior in the way of Allah (i.e., provides him with the means for jihad), he will receive a reward equal to that of the warrior. And whoever looks after the family of a mujahid in his absence with goodness or spends on his dependents, he too will receive a reward equal to that of the mujahid.”
