Reconnoitering the Enemy's Weapons

News about the enemyís marching were conveyed to the Messenger of All‚h [PBUH], so he sent out Al-Aslami with orders to mix with people, stay with them so that he would be able to know their news and to convey it to the Messenger of All‚h [PBUH] when he turns back. That was exactly what he managed to do.
