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.”

It is narrated from Sayyiduna Zaid bin Thabit (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 path of Allah, he will receive a reward equal to that (which the warrior receives), and whoever looks after the family of a Mujahid in his absence with goodness or spends on his family, he will also receive a reward equal to that (of the Mujahid)."

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The warrior (ghazi) will receive his reward, and the one who equips him will receive (double reward): one his own reward and the reward of the warrior."
