God doesn't have a name in that sense. He has titles, but no real name and it's absurd for eternal being that preceded languages to name himself with one particular language. The closest thing that comes to being his name, is his holy spirit and image from him. That metaphorically is what he has chosen as his name.
Why? A name is how something is referenced, and the image of God/face of God/holy spirit is by how God is referenced. The light of God in his chosen is by how we recall God.
Right now, if you see God, you are not seeing him directly, but through his greatest sign, the leader and guide that is a spirit from God encompassing everything in the heavens and earth.
I should make a topic how "God's greatest name" has always been misunderstood to be a title, when it's more of a metaphor of his light and chosen way to be referenced, that is his word of light brought to life. This is true in the old books, in the Quran, and hadiths.
Another synonym to name of God, is the "God's word".
The holy name of God is so passed into the named, that Quran says "Allah is the light of the heavens and earth". The signs of God in the Unseen, the highest type, is so connected to God, that is why Quran says "You did not throw when you threw but God threw" and said "two bows or closer still".
The believers are to tun to God through the light of his face.
