Muhammad ibn al-Hasan ibn Ahmad al-Saffar, from al-Hasan ibn Ahmad ibn Bashshar, from Ya'qub, from al-Abbas al-Warraq, from a man whom he named, from Abu Abdillah عليه السلام, peace be upon him, who said: Imam عليه السلام said: "If a people go on a military expedition without the permission of the Imam (of Ahlul Bayt عليه السلام) and gain booty, the entire booty belongs to the Imam (of Ahlul Bayt عليه السلام). And if they go on a military expedition by the command of the Imam (of Ahlul Bayt عليه السلام) and gain booty, then the khums belongs to the Imam (of Ahlul Bayt عليه السلام)."
