Musannaf Ibn Abi Shaybah 35189 — What they said on dividing conquered

Malik bin Aws bin al-Hadathan (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) said: The wealth of Banu al-Nadir, which Allah granted to the Messenger of Allah (peace and blessings be upon him), came to the Muslims without fighting; there was no need for battle in it. And this wealth was exclusively for the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) would hold back from it his expenses for the year, and whatever remained he (peace and blessings be upon him) would set apart for horses and weapons, as preparation for using them in the path of Allah.
