Musnad al-Humaydi

Sayyiduna Jabir (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "The best prayer is that in which the standing (qiyam) is long, and the best jihad is that in which blood is shed and the horse's legs are cut, and the best charity is that which a poor person gives through effort. (The narrator is in doubt, perhaps these are the words:) that when charity is given, then after that the person remains well-off."
