Jaysh al-Muwahhideen is a group of people who live in a country called Syria. They have a special way of thinking about God, and they believe that there is only one God and no one else should be worshipped except for Him. They call this idea "tawheed."
These people have created a group to try and make their beliefs stronger and spread them to other people. They call themselves Jaysh al-Muwahhideen, which means "Army of the Monotheists" or "Army of the Believers in One God."
The leaders of this group believe in the use of force to make their beliefs known and protect themselves from others who may not agree with them. They have been involved in some fighting in their country and have been listed as a terrorist organization by some countries.
It is important to remember that not all people who believe in tawheed are a part of Jaysh al-Muwahhideen, and not all Muslims believe in tawheed in the same way. It is also important to remember that violence and hurting others is never the way to solve problems or get your point across.
