What does the Catechism say? Who cares what the "heading" is? Did you READ the text? Do you agree with it? Do Muslims worship the same God as you do?
Do they? Do you?
A simple "Yes" or "No" would suffice.
But, since you MUST accept the teaching of the Roman Catholic Church's Catechism, then you must agree, right?
Do Muslims believe is the one true living God? I think not.
I do think that leaves you (and all Roman Catholics) in a bit of a quandary.

How many Gods do you believe exist?
No quandry at all. Muslims follow an imperfect understanding of God — just like Protestants do.
