Many Muslims believe that Christianity is a poly-thiestic religion because we worship the Trinity.
I have had some modest success in challenging this idea by suggesting that a man can have many roles; he can be a father, brother, husband, etc: WE can take on many roles, and so does our Father. This is overly simplistic, but I believe that it is a good first step in challenging a very large misconception about Christianity.
This is an ancient controversy. The Arian’s position was firmly rejected at the Council of Nicaea in 325 AD. The Arians held basically that Christ was not God (a lesser God, if you will), due to his physical nature. The Council rejected their argument and Constantine backed the Council's decision.
The issue was put to rest before Muhammad, so the argument you mentioned is simply some Muslims not doing their homework (a failing that is not uncommon to other religions as well).

I think a better way is to tell them that man and wife are “one” in the Old Testament Hebrew the same way father, son, and holy spirit are “one”. The Hebrew word “echod” Aleph-Chet-Dalet is the same word for both.
