It's not the response you want. It is, however, an analogy and speaks directly to the point.
To equate the Triune God of Christianity to allah of Islam, which is what you want to do, is to engage in a philosopher's method of abstraction and indifferentism. You want to leave out the details. The details are what matter most.
If you prefer a philosopher's god of universal characteristics, then please do so.
It's a very bad one that DOES NOT speak to the point at all.
You are evading the question. Is there just one God, as I understand Christianity adn most other religions to teach, or are there many gods, as in Paganism?
