He is Allah, the unknowable, the inaccessible, all-powerful and merciful creator. So one argument is he's using the Arabic word for God. He's using Allah. Now another argument, counterargument, would be, well, he's just using the language that his followers knew, and many of his followers were Muslim, and so would have used the word Allah for God. But he is not saying that it necessarily has to be the exact concept of God as in Islam. Now this is from Kabir. Someone sets up a stone idol, and all the world worships it as the Lord.
