God Not Merely The First Cause Or The Necessary Being
Your question is not clear, but as a matter of principle, Islam doesn’t stop us from researching into any form of knowledge. The only exception can be when we gain knowledge with evil intentions, or the implementation / application of such knowledge would be immoral. As far as God is concerned, the only way for us to gain any reliable knowledge about Him is through the word of God itself. Ilm-ul-kalam can’t add or take away anything from it. Almost every idea in kalam has been challenged by kalam itself or the greater subject of philosophy, so in the end we’re only left with the scriptural description of God anyway.
