Tefillin and the dead arm

There's a Lubavitcher Yungerman, we’ll call him Moshe, who is an immigration lawyer for a multi-faceted law firm. Recently, the insurance litigation department of his firm took a client, an Iraqi gentleman, who was injured in a car accident and completely and permanently lost use of his left arm. The insurance company agreed to settle for half a million dollars. In the course of their dealings, they discovered that he had some immigration issues, so on this past Monday they sent him to Moshe's department to get things ironed out. Moshe landed the case. In the course of his interview he asked the Iraqi for his mother's maiden name, and he said "Zecharya". Moshe reacted with surprise and said "That's a Jewish sounding name!" "I know," said the Iraqi, "My mother was Jewish." "You know that means that you are Jewish!" Moshe informed him. "Yes," he said, "So I've been told."

"You know what?" said Moshe. "I have some Teffilin here. How would you like to do a mitzvah?" Moshe went on to explain to him what a mitzvah is and what Teffilin are. The gentleman agreed to put on Teffilin. As soon as he began, Moshe realized that it would be somewhat of a challenge, as the man could not move his left arm at all. Moshe had to manipulate the arm completely in order to get the Teffilin on, wrapped around correctly, and then removed.

Tuesday morning, this Iraqi showed up at the law office and demanded to speak with Moshe. As soon as he saw him, he expressed with great astonishment, "You would never believe this! When I woke up this morning, I have complete mobility in my left arm - something the doctors pronounced to be impossible! I am sure that it is due to the Teffilin that we put on yesterday!"
