Sayyiduna Umar (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) used to spend on his family for a year from the wealth of Banu Nadir. This was from the wealth which Allah Almighty had granted to His Messenger (peace and blessings of Allah be upon him) as fay. The Muslims had neither ridden horses nor camels for it. Then whatever remained, he would spend it in the way of Allah for the preparation of horses and weapons.
