All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The Name "Allaah" can be translated as 'God' for new Muslims who do not know Arabic language, just as we translate for them the meanings of the Quran and Ahadeeth in order to teach them the religion of Islam.
As for translating the name "Allaah" with 'God' while translating the meaning of the Quran or Hadeeth or books of Islamic knowledge, we do not think that this is permissible. Rather, it is an obligation to leave the name of Allaah in its original form as it is pronounced "Allaah". This is because, the name Allaah is the proper name of our Lord, Allaah. Besides, the Name Allaah demonstrates all His other Beautiful Names. Allaah Says (what means): {And (all) the Most Beautiful Names belong to Allaah, so call on Him by them, and leave the company of those who belie or deny (or utter impious speech against) His Names. They will be requited for what they used to do.}[Quran 7:180].
Moreover, the Prophet said: "Indeed, Allaah has ninety-nine names, one hundred less one; and he who memorizes them all by heart (and acts upon their implications) will enter Paradise." [Al-Bukhari and Muslim]
The name "Allaah" is different from the word "God" which only means a deity and does not in any way indicate deeming Allaah far from being likened to false deities that are worshipped besides Him. The proper meaning of Laa Ilaaha Illa Allaah, is: "There is no deity worthy of being worshipped except Allaah".
Allaah Knows best.
