They carried away a purse of Huyayy ibn Akhtab who was killed before (the battle of) Khaybar. He took away the ornaments of Banu an-Nadir when they were expelled.
The Prophet (ﷺ) asked Sa'yah: Where is the purse of Huyayy ibn Akhtab?
He replied: The contents of this purse were spent on battles and other expenses. (Later on) they found the purse. So he killed Ibn Abu lHuqayq, captured their women and children, and intended to deport them.
They said: Muhammad, leave us to work on this land; we shall have half (of the produce) as you wish, and you will have half. The Messenger of Allah (ﷺ) used to make a contribution of eighty wasqs of dates and twenty wasqs of wheat to each of his wives.
