Sorry Rudy but you can not be a devout Muslim and an American Citizen.
Islam requires the Koran to be superior to any Constitution or set of laws or morals, it is the final word on all things Islam, well except for the looney Imams that write Hadiths and Fatwahs.
I say you are wrong in it’s understanding;
Try Matthew6:24; New International Version;
“No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.
How many of us serve 2 or more masters? The same can be said of those who follow the Islamic faith & are American Citizens.
