The Banu Naldir and the Khoraysh

The Banu Naldir actually gave supplies and food and water to the small entourage of Abu Sufyan. They hosted him to reinvigorate and reinforce him before he attacked Medina. The Muslims were able to capture Sawik, a lot of porridge but they didn't have their men back. But at least he could now take a bath because he killed two of the insat.
