Allah is the personal name of God, in Arabic and Aramaic (the language of Jesus). It cannot take plural/feminine form, whereas, the word "God" is a title, not a name, and can take plural/feminine forms. Allah is the personal name of the one true God.
Nothing else can be called Allah. The term has no plural or gender. This shows its uniqueness when compared with the word god can be made plural, gods, or feminine, goddess. It is interesting to notice that Allah is the personal name of God in aramaic, the language of Jesus and a sister language of Arabic.
No! Allah (Arabic: الله, Allah,) is the standard Arabic word for God, it is the same word used by Arabic-speakers of all faiths, including Christians and Jews, in reference to "God "The word is used by Arab Jews and Arab Christians in the Arabic bible as well as a standard translation for the word GOD. If you pick up an Arabic Bible, you will see the word "Allah" being used where "God" is used in English. This is because "Allah" is the only word in the Arabic language equivalent to the English word "God" with a capital "G"
Every hotel and motel has a Bible. Next time you see one look in the introduction, you will find samples of the different languages they have translated, have a look at the Arabic translation you will find the word Allah.
Quotation from Arabic bible, the translation of Genesis 1:1
" Fee al-badi' khalaqa Allahu as-Samaawaat wa al-Ard . . ."
* since "Allah" is simply the Arabic word for "God" – and there is only One God. Let there be no doubt – Muslims worship the God of Noah, Abraham, Moses, David and Jesus- peace be upon them all. However, it is certainly true that Jews, Christians and Muslims all have different concepts of Almighty God. For example, Muslims like Jews reject the Christian beliefs of the Trinity and the Divine Incarnation. This, however, doesn't mean that each of these three religions worships a different God – because, as we have already said, there is only One True God. Judaism, Christianity and Islam all claim to be “monotheistic Faiths", However, Islam teaches that other religions have, in one way or another, distorted and nullified a pure and proper belief in Almighty God by neglecting His true teachings and mixing them with man-made ideas.
* It is interesting to note that the Aramaic word "El", which is the word for God in the language that Jesus spoke, is ertainly more similar in sound to the word "Allah" than the English word "God". This also holds true for the various Hebrew words for God, which are "El" and "Elah", and the plural form "Elohim". The reason for these similarities is that Aramaic,Hebrew and Arabic are all Semitic languages with common origins.
* If one understands the root meaning of the word "Allah", this point should become clear.In the Arabic alphabet, since it does not have capital letters, the word for God (i.e. Allah) is formed by adding the equivalent to the English word "the" (Al-) to the Arabic word for "god/God" (ilah). So the Arabic word "Allah" literally it means "The God" – the "Al-" in Arabic basically serving the same function as the capital "G" in English. Due to the above mentioned facts, a more accurate translation of the word"Allah" into English might be "The One-and-Only God" or "The One True God".
In fact, Islam is the only religion which teaches the existence of a PERFECT God. A perfect God means that there is no sharer in His Nature and His Attributes. Islam rejects characterizing God in any human form or depicting Him as favoring certain individuals or nations on the basis of wealth, power or race. He created the human-beings as equals. They may distinguish themselves and get His favor through virtuen and piety only.
If the Creator is eternal and Everlasting, then His attributes must also be eternaland everlasting. He should not lose any of His attributes nor acquire new ones. If this is so, then His attributes are absolute. Can there be more than one Creator with such absolute attributes? Can there be for example, two absolutely powerful Creators? A moment's thought shows that this is not feasible. The Quran summarizes this argument in the following verses:
"God has not taken to Himself any son, nor is there any god with Him: For then each god would have taken of that which he created and some of them would have risen up over others." (23:91)
"And Why, were there gods in earth and heaven other than God, they (heaven and earth)would surely go to ruin." (21:22)
* The Quran tries to promote this feeling of gratitude by repeating the attributes of God very frequently. We find most of these attributes mentioned together in the following verses of the Quran:
He is God; there is no god but He, He is the Knower of the unseen and the visible; Heis the All-Merciful, the All-Compassionate. He is God, there is no God but He. He is the King, the All-Holy, the All-Peace, the Guardian of Faith, the All-Preserver, the All-Mighty, the All-Compeller, the All-Sublime. Glory be to God, above that they associate! He is God the Creator, the Maker, the Shaper. To Him belong the Names Most Beautiful. All that is in the heavens and the earth magnifies Him; He is the All-Mighty, the All-Wise." (59:22-24)
"There is no god but He, the Living, the Everlasting. Slumber seizes Him not, neither sleep; to Him belongs all that is in the heavens and the earth. Who is there that shall intercede with Him save by His leave? He knows what lies before them and what is after them,and they comprehend not anything of His knowledge save such as He wills . His throne comprises the heavens and earth; the preserving of them oppresses Him not; He is the All-High, the All-Glorious." (2:255)
