It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) sent a detachment towards Najd, and Ibn Umar (may Allah be pleased with them both) was among them. Their shares reached twelve camels each, and they were each given one more camel, and the Prophet (peace and blessings be upon him) did not change it.
