Actually there are many similarities.

• Both have a self-proclaimed prophet that cast doubt on the accuracy and completeness of the original scriptures in order to get his own scriptures adopted.
• Both prophets used their power as spiritual leader to marry many times and in violation of Old Testament commands and to gather possessions to themselves.
• Both actually started out rather violent. The U.S. Calvary was called in to stop Mormon's from attacking wagon trains passing through.
• Both demoted Jesus from being God to being just a prophet in Islam and just a man who was promoted to Godhood in Mormonism.

And, an interesting difference:

The Mormon doctrine of Eternal Progression asserts that God was once a man,and that humans may become gods themselves. All of this is emphatically rejected by Islam, which views these teachings as polytheistic.

Both have ‘scared scriptures’ of dubious authorship..........
