[Jael]

Oh Yes, Muslims do deny the Father.

John 1:1  ¶In the beginning was the Word, and the Word was with God, and the Word was God.

2  The same was in the beginning with God.

3  All things were made by him; and without him was not any thing made that was made.

4  In him was life; and the life was the light of men.

5  ¶And the light shineth in darkness; and the darkness comprehended it not.

Islam does not recognize Jehovah. They do not worship Him, the Great I Am, the Ancient of Days.

They worship a monotheistic godling called Allah. He has nothing in common with the great Jehovah.
