In August 625 it was Ibn Maslamah who brought the message to the Nadir tribe that Muhammad wanted them to leave their land within ten days or he would cut off their heads. They replied: "We did not think that an Aws man would bring such a message!" Ibn Maslamah said, "Hearts have changed." Later, when the Nadir tribe surrendered to Muhammad and were expelled from Medina, it was Ibn Maslamah who supervised their exit and collected all their confiscated property and weapons.
