Sayyiduna Ibn Umar (may Allah be pleased with them both) said that the Prophet (peace and blessings be upon him) dispatched an army towards Najd, and Ibn Umar (may Allah be pleased with them both) was in that army. Ibn Umar (may Allah be pleased with them both) related that the army's shares reached twelve camels each, and that force was given one more camel each, so those of the detachment had thirteen camels each, and those of the army had twelve camels each.
