The Muslims prefer calling Allah (swt) with His Name Allah, instead of the English word ‘God’. The Arabic word Allah is pure and unique, unlike the English word God which can be played around with.
If you add ‘s’ to God, it becomes ‘gods’ that is plural of God. Allah is one and singular, there is no plural of Allah. If you add ‘dess’ to God, it becomes ‘goddess’ that is a female God. There is nothing like male Allah or female Allah. Allah has no gender. If you add father to God, it becomes ‘godfather’. “He is my Godfather” means that “he is my guardian”. There is nothing like Allah Abba or Allah father in Islam. If you add mother to God it becomes ‘godmother, there is nothing like Allah Ammi or Allah Mother in Islam. If you put tin before God, it becomes tin god i.e. a fake God, there is nothing like-tin Allah or fake Allah in Islam. Allah is a unique word, which does not conjure up any mental picture nor can it be played around with. Hence, the Muslims prefer the name Allah when referring to the Almighty Creator. But sometimes while speaking to non-Muslims we may have to use the inappropriate word God for Allah.
