"Inshallah" is "Allah wills", not "God wills".
Allah is not God.
Allah is not another word for God.
Allah is Hubal, aka HaBa'al, the Ba'al of the Moabites, the god of Mohammad's family that Mohammad promoted to his followers.
Mohammad cleaned out all the other pagan idols of the kaaba, but not HuBa'al. That idol remains to this day, or more clearly, the meteorite part of the idol that survived to this day. In a silver encasing.
And no, for one last time, "Allah" is not just the Arabic word for God; "Allah" has nothing in common with the God of Abraham, Isaac and Jacob; in fact, it is likely the pagan god of Abraham's father, whom Abraham abandoned to head west to the Promised Land.
Easy way to tell the difference:
The God of Abraham, Isaac and Jacob has one beloved and begotten Son, Christ Jesus, Yehoshua/Yeshua in the Hebrew/Aramaic.
Allah has no children, and is in fact a child of El, the main demon god of the Canaanites, with sister Ashteroth and brother Molech.
When Elijah said "Choose this day whom you will worship, God, or Ba'al", on Mt. Carmel, it's the same choice today.
Choose this day whom you will serve.
