It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent this message to Banu Lahyan: "From every two men, one should go forth." Then the Prophet (peace and blessings be upon him) said to those who remained behind: "Whoever among you becomes a good and benevolent guardian of the family and wealth of the one who goes forth as a Mujahid, for him there will be a reward equal to half the reward of the one who goes forth."
