[St_Thomas_Aquinas]

"The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind's judge on the last day." Catechism of the Catholic Church

They occupy the first place amongst those who acknowledge the Creator, i.e., non-Jewish theists. They come after Christians and Jews, since their understanding of the nature of God is far less perfect.

The Catechism on Islam

[verga]

They come after Christians and Jews, since their understanding of the nature of God is far less perfect.

I would say "severely disordered."
