Re: Malaysia court rules non-Muslims can’t use ‘Allah’
Nice try but no fact just fabricated claim … brother you can try truth to justify your beliefs, but please do not take refuge in lies and propaganda that could misguide some (as I believe it is due to your post Captain1 raised question in post 47).
In Arabic … Al is used to make something definitive.
ilah = god (any god)
Al-ilah or Allah = The God, The supreme deity, Creator of everything.
Arab kuffars used ilah for any god … and Allah for supreme God. Not only kuffars, but all who used to speak Arabic, including Jews and Christians, used to use Allah for the ‘Supreme God’ or ‘God the creator’.
Now, I know you would not feel satisfied however obvious a thing maybe, unless one do not quote Quran or hadith to justify the claim. 
So, here it is: Even though it can be proven from many ayahs, let see ayah 4:171 (mentioned below). In this ayah, Allah is telling ‘people of the book’ that ilah is only one and that is Allah … where ‘Allah means the God’ and ‘ilah means god’. From ayah it is obvious that people knew Allah as Supreme God.

O people of the scripture (Christians)! Do not exceed the limits in your religion, nor say of Allah aught but the truth. The Messiah ‘Îsa (Jesus), son of Maryam (Mary), was (no more than) a Messenger of Allah and His Word, (“Be!” – and he was) which He bestowed on Maryam (Mary) and a spirit (Ruh ) created by Him; so believe in Allah and His Messengers. Say not: “Three (trinity)!” Cease! (it is) better for you. For Allah is (the only) One Ilah (God), glory be to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs. (Surah An-Nisa:171)
Thus, Quran confirms that Jews and Christians used to recognize and worship the creator calling him ‘Allah’ … and that is why when God talked about himself to these people he used the term Allah (whom these people recognised and worshipped), letting people know that other than Allah there is no ilah. Obviously, from ayah it is clear that ‘Allah’ was known and unquestionable as ‘supreme Being’.
From ayah, one can see that word ilah is used to define god and Allah is used to define the only god or ‘Supreme God’. In above ayah Allah is telling people of the book that there is only one god (ilah) who is the supreme God (Allah).
In ayah 4:82 Allah is mentioned in general terms, showing that all who speak Arabic, even kuffars of Mecca, they used to recognise and worshipped Allah as ‘supreme Being’ (The god, creator of everything).

Afala yatadabbaroona alqur-anawalaw kana min AAindi ghayri Allah i lawajadoo feehiikhtilafan katheera
“Do they not then consider the Quran carefully? Had it been from other than Allah they would surely have found therein much contradictions.” (Surah An-Nisa 4:82)
So … from Quran (above ayahs) it is clear that Kuffars as well as people of book used to remember, recognise and worship Allah as ‘Supreme Being (creator)’ whom Christians used to also consider ‘God the father’. These people recognised Allah so much as Supreme Creator that Allah tells them that they should accept the message (Quran) from him, and also told them that if Quran was not from Allah (God these people worshipped as supreme god = Allah) then Quran would have had lot of contradictions … shows, Allah as supreme God was known and unquestionable and that he could not send anything contradictory (known to all).
Now let come to hadith and historical facts to prove that kuffars and people even before Islam used to know and worship Allah as the Supreme Being and creator.
1: Prophet (SAW) father name was Abd-Allah (servant of Allah)… or Abdullah. … shows that Quraish even before birth of Prophet (SAW) used to know and worship Allah.
2: Let look at hadith referring to Mahada-e-Hudaybia (given below). In that treaty agreement:
A: Ali (RA) under the instruction of Prophet (SAW) wrote ‘Bismillah-ir-Rahman-ir-Rahim’ (In the name of Allah, most gracious and most merciful) … Quraish protested … and asked it to get replaced with ‘Bi-ismika Allah umma’ (in thy name, O Allah).
Shows that for Quraish, Allah was supreme Being whom they knew and worshipped (as God supreme) and also used to mention his name for anything they start.
B: Ali (RA) under instruction of Prophet (SAW) wrote … Mohammad Rasul-Allah (Mohammed, prophet of Allah) … Quraish protested … protested what?
Well, Quraish said that if they believed Prophet (SAW) as messenger of Allah (Rasul-Allah) then there would have been no conflict (because for them Allah was God supreme)… but they do not believe that Prophet (SAW) is messenger of Allah. So for Quraish Allah as ‘Supreme God’ was known … but their doubt was on Prophet-hood of Prophet (SAW). It shows that Quraish used to recognise that Allah is the Supreme God whom they worship, else if Quraish did not used the word Allah for supreme God then their questioning and protest was meaningless.
Sahi Muslim:* Book 019, Number 4404:*
(http://www.usc.edu/org/cmje/religious-texts/hadith/muslim/019-smt.php#019.4404)
It has been narrated on the authority of Anas that the Quraish made peace with the Prophet (may peace be upon him). Among them was Suhail b. Amr. The Prophet (may peace be upon him) said to 'Ali: Write" In the name of Allah, most Gracious and most Merciful." Suhail said: As for" Bismillah," we do not know what is meant by “Bismillah-ir-Rahman-ir-Rahim” (In the name of Allah most Gracious and most Merciful). But write what we understand, i. e. Bi ismika allahumma (in thy name. O Allah). Then, the Prophet (may peace be upon him) said: Write: “From Muhammad, the Messenger of Allah.” They said: If we knew that thou welt the Messenger of Allah, we would follow you. Therefore, write your name and the name of your father. So the Holy Prophet (may peace be upon him) said: Write" From Muhammad b. 'Abdullah." They laid the condition on the Prophet (may peace be upon him) that anyone who joined them from the Muslims, the Meccans would not return him, and anyone who joined you (the Muslims) from them, you would send him back to them. The Companions said: Messenger of Allah, should we write this? He said: Yes. One who goes away from us to join them-may Allah keep him away! and one who comes to join us from them (and is sent back) Allah will provide him relief and a way of escape.
So, it shows that Kuffars, Christians, Jews … well, anyone whose language was Arabic used to recognise and worshipped God supreme by the name ‘Allah’, even before the birth of Prophet (SAW).
