Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrated: The Messenger of Allah (peace and blessings be upon him) sent a detachment towards Najd, and Abdullah (himself) was among them. We obtained many camels as spoils, and our shares reached twelve camels each, and the Messenger of Allah (peace and blessings be upon him) gave us one extra camel each as a bonus (nafl).
