Muslims call God "Allah" instead of "God" for several reasons: 1) The word "Allah" is pure and unique, unlike "God" which can be modified in various ways that distort its meaning. 2) Adding letters to "God" can change its meaning, like making it plural ("Gods") or referring to a female deity ("Goddess"), but "Allah" always remains singular and without gender. 3) Terms like "Godfather" or "Godmother" could not be made from "Allah" in the same way as they can be from "God". 4) "Allah" cannot be used to create fake or modified terms for God

1. Q53.
Why do Muslims call God, ‘Allaah’? Is ALLAAH"
MORE APPROPRIATE THAN GOD?
Answer.
1. A person can play around with the English word ‘God’:
Muslims prefer calling Allah (swt) as Allah, instead of the English word ‘God’. The Arabic
word ‘Allaah’ is pure and unique, unlike the English word ‘God’ which can be played
around with.
2. God + s = Gods:
If you add the alphabet ‘S’ to ‘God’, it becomes ‘Gods’, that is plural of God. Allaah is
One and Singular. There is no plural of Allaah.
3. God + dess = Goddess:
If you add ‘dess’ to ‘God’ it becomes ‘Goddess’, that is a female God. There is nothing
like male ‘Allaah’ or female ‘Allaah’. Allaah has no gender.
4. God + Father = Godfather:
If you add the word ‘father’ to ‘God’, it becomes ‘Godfather’. "He is my Godfather" i.e. he
is my guardian. There is nothing like ‘Allaah Abba’ or ‘Allaah father’ in Islaam.
5. God + Mother = Godmother:
If you add the word ‘mother’ to ‘God’ it becomes ‘Godmother’. There is nothing like
‘Allaah Ammi‘ or ‘Allaah mother’ in Islaam.
6. Tin + God = Tingod:
If you put ‘tin’ before ‘God’ it becomes ‘Tin-God’ i.e. a fake God. There is nothing like ‘tin
Allaah’ or ‘fake Allaah’ in Islaam.
7. Allaah is an Unique Word:
‘Allaah’ is an unique word, with which can neither conjure up a mental picture, nor can it
be played around with. ‘Allaah’ is the name mentioned for the One Unique and True God,
in the Qur’an. Therefore, Muslims prefer calling God, ‘Allaah’. But sometimes while
speaking to non-Muslims we may have to use the inappropriate word ‘God’, for Allaah.
