Personally, I believe that we as Muslims can't stop the Kaffirs from using whatever language to publish their scriptures or whatever?
If we are to address the current issues of the Catholic Church here in Malaysia from using the word / term 'Allah' to represent what they now come to claim as their God whilst sticking to the Concept of Trinity, we have our grounds to protest the very notion for it clearly obliterates such a claim.
Let's refer to Surah Al Ikhlas, Chapter 112 in the Holy Al Qur'an
بسم الله الرحمن الرحيم
We can't stop them from using Malay as a medium to translate their religious texts. Malay as a language is universal. So is any other language.
None can stop us from publishing translations of the meanings of the Holy Quran in any other language.
It should be the same for any other faith or belief.
What we need to do is to improve the understanding of Al Islam amongst the ummah, both here in our country and worldwide.
As we all know, the levels of understanding of true Islamic teachings and putting them to practice in the real sense of the word varies from country to country and even amongst the various tribes and denominations of the Muslims of this world.
I was just writing and doing a study on the 'Untouchables' amongst the Muslims of India.
They have introduced a system of castes amongst the Muslims of India. We have the same sort of differentiating amongst our ummah here too based upon one's lineage and ancestry.
Its not as pronounced here as over there in India but we know that some of us do that.
Back to the matter of the Christians here wanting to call their Trinitarian Concept of God as 'Allah'. We need to dispel such unwarranted claims the educated and honorable way. Here is the late Allahyarham Syeikh Ahmed Deedat clarifying the delusions regarding Allah the Almighty to be what the Christians claim to be the 3 in 1 'Concept of Godhood which they say is their Trinitarian 'God':
As learned Muslims, we ought to help clear the confusion that the Christians have with regard to the One and Only True God of us all by such crystal clear explanations backed by facts, not with emotional erratic tantrums or outbursts.
Neither by rough slipshod protests and half-baked arguments not backed by the Holy Al Quran and authentic Hadiths.
Giving way to our human emotions is one thing but we are commanded by Allahu Ta'ala to argue with them (Non Muslims) in ways that are best and most gracious. Surah An Nahl Chapter 16 Verse 125.
Surat An-Naĥl (The Bee) - سورة النحل
Why can't we do that?
