Even Christians say Allah

Even Christians say Allah
Just ask the Christians of the Middle East
The word Allah is even known in some Western circles
In fact, Allah was known to Arabs before Islam in Arabia

“Allah (English pronunciation: /ˈælə/ or /ˈɑːlə/; Arabic: الله‎ Allāh, IPA: [ʔɑlˈlɑː] ( listen), [ʔalˤˈlˤɑː]) is the Arabic word for God (literally “the God”, as the initial “Al-” is the definite article).[1][2][3] It is used mainly by Muslims,[4] Arab Christians, and often, albeit not exclusively, by Bahá’ís, Arabic-speakers, Indonesian, Malaysian and Maltese Christians, and Mizrahi Jews.[5][6][7]”
