First thing, there is no such language as 'Muslim'. The language that the Qu'ran was written in was Arabic and followers of the religion of Islam are called Muslims. So, now that we've got that straight, this is how you say "God be with you" in Arabic, which is what I assumed you meant.
Allah ya-koun ma'ak: God be with you
But nobody says this...
If you have any more questions, or need clarification, please feel free to message me
Muslim (Islam) is a religion, not a language.
The Karon (Karen) Is The Muslim Bible If You Are Muslim Then Shame On you they worship god only god
The God of Islam, or the Muslim God, is Allah.
Muslim ascetics, like all Muslims, believe that there is no god but God and that Muhammad is the Messenger of God. They are monotheists and believe in the Qur'an.
Sword of God = Gladius Dei
Allah
A: Allah
God name is Allah, God of Islam (Muslim )
Muslim isn't a language, but both Christian Arabic speakers and Muslim Arabic speakers refer to God as Allah.
responsum Dei
ALLAH!
Arabs may be Muslim, Christian or Jewish, in which case their God is the unnameable God of Abraham; or they may belong to any other religion. If you mean "What do the Muslim call God?" the answer is: al Lah ("the God").
