Who Owns Allah?

"The usage of the word Allah is not an integral part of the faith in Christianity. The usage of the word will cause confusion in the community," decided a Malaysian court. Only Muslims can use Allah. It's a ridiculous decision and it goes against the Quran and the teachings of Islam. The Quran introduces Allah as Lord of the Universe describes the Prophet, mercy to humankind, and declared itself guidance to humanity. Nowhere does it say that Allah is for Muslims only, or the Quran for the followers of Islam only or the Prophet was sent to Muslims only. 
Islam did not invent the word, Allah. It was in vogue in pre-Islamic Arabia. The Quran makes references to the polytheists who used the word of Allah. One of the cousins of Prophet's wife Khadeeja, used the word Allah when speaking to Prophet immediately after he had received the first revelation.
In the Middle East, Arabic-speaking Christians use the word, Allah. 
Allah is not monopolized by Muslims. Allah is neither Muslim nor Christian, now Jewish. He is Allah, the creator of the universe and everything that exists in the universe including Christians and Jews. To say that only Muslims or Malays can use this word is an offense to Islam.
What are Muslim scholars doing? Why they don't speak up at this nonsense.  Let us hope that a higher court in Malaysia turns this decision down.
