Allah is also the name by which Arabic Christians refer to God.

You continue to state the issue in the incorrect manner, implying that the Church has equated the Moslem view of God with the truth. I will quote once more what you, as a Catholic, are beholden to accept as the teaching of the Church, whatever your personal opinion on the matter may be:

841 The Church’s relationship with the Muslims. “The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and [b:3poh31f0]together with us they adore the one, merciful God[/b:3poh31f0], mankind’s judge on the last day.”

Whatever your example, the rise of the Moslem people was promised by God to Abraham.
