They can keep Allah.
Which brings up the interesting question -— before Islam was born, prior to Muhammad — how did the people in that region refer to GOD ?
I’m sure most were polytheistic, but there SHOULD BE monotheists in the Arab region. How was God referred to in their language ?
In China for instance, long before Buddhism and Taoism, the Chinese had a concept of one God who they refer to as Shang Di ( Emperor of Heaven ). The missionaries who went to China to preach the Gospel have always used this term and it is still used in the Chinese Bible.
I wonder what term was used to refer to THAT one God in Arabic BEFORE Muhammad formed Islam....
I’ll be sure and burn down the mosque a few miles from my house the next time I hear Muslims saying Jesus was a prophet. (sar.)
