The Banu Khayunukha and the Khaziribites

The Banu Khayunukha in the days of Jahiliya had two main representatives or allies from Yathirib from old Medina. They reached out for help to these two people you are our allies, they said. The Muslims surrounded them for half a month and laid siege until finally they decided there is no alternative the water is going to run out. He marches straight to their camp where they are now prisoners and he demands the Muslims release them.
