Just as well. The Christian God of Abraham, Isaac, and Jacob is NOT Allah. The God of Israel and of Christianity should NOT be confused with the Allah of Mohammedans.
The word "Allah" in Arabic means "God." Arabic-speaking Jews and Christians call God "Allah." In Arabic translations of the Bible, Genesis 1:1 says "In the beginning, Allah created..."
Yet it is. Allah simply means "God" in Arabic. Arab Christians were calling God "Allah" before Islam existed, and they still do today.
I've seen an infinite number of claims to the contrary on FR, of course, but simply asserting something you want to believe doesn't make it true. Arab Christians are running around today routinely using the term "Allah" for God and they don't care what you think or assert.
There are hundreds of thousands of Arabic-speaking Christians in Syria and Lebanon, but it's probably nearly a non-issue in Malaysia. I wonder what ticked off the sultan? Christian missionary activity?
