"Tell me who you are and what is happening, or the full force of the Iraqi Army will crush you. We will pound you with missiles and artillery, and when you retreat we will laugh and kick your backsides." Al-Sahaf might not know what was going on, but he did know that he couldn't let those villains get the upper hand.
Saruman looked at the stranger in glasses wearing a black beret. He knew the bewildered man could have no connection to the invading Ents, and that the wisest course of action would probably be to kill this delusional apparition, but his words were strangely compelling. He had a power akin to that of Wormtongue, and Saruman thought he might be able to use that to his advantage. Also, there wasn't a lot to do while under siege, and Go Fish with two people was getting boring.
"You are in the tower of Orthanc in what was the city of Isengard. We are being attacked by tree-creatures called Ents. I am the great wizard Saruman, and this is Grima." Muhammed thought on this, and then his eyes lit up. Figuratively speaking, of course, and not in the "my pupils are on fire" sort of way.
"Praise be to God! I have protected and informed the Iraqi people when they thought they were being invaded by proclaiming the truth, and now I have been sent to aid you. Truly, the invaders are godless infidels. I tell you, there are no Ents in Isengard!"

A/N: Even though Saruman is speaking Westron and al-Sahaf is speaking Arabic or broken English, there is no language problem because al-Sahaf believes that everyone will understand him.
