It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "A detachment was sent towards Najd: their share became twelve camels each, and the Noble Prophet (peace and blessings be upon him) also gave us one camel each as a reward."
