Musnad Ahmad 171

Translation

✧ The wealth of Banu al-Nadir was among that which Allah granted His Messenger ﷺ as fay', for the Muslims did not expend horses or camels to obtain it. It belonged exclusively to the Messenger of Allah ﷺ. He used to spend on his family from it their yearly expenses—and once he said: their yearly provision—and what remained he allocated for horses and weapons as equipment in the cause of Allah, Mighty and Majestic.
