Part One: on the identity of Allah and the pre-Islamic moon god
The well-known Middle East scholar H. Gibb has pointed out that the reason that Muhammad never had to explain who Allah was in the Quran is that his listeners had already heard about Allah long before Muhammad was ever born. (1)
Dr. Arthur Jeffery, one of the foremost Western Islamic scholars in modern times and professor of Islamic and Middle East Studies at Columbia University, notes:
"The name Allah, as the Quran itself is witness, was well known in pre-Islamic Araabia. INdeed, both it and its feminine form, Allat, are found not infrequently among the theophorous names in inscriptions from North Africa." (2)
The word "Allah" comes from the compound Arabic word, al-ilah. Al is the definite article "the" and ilah is an Arabic word for "god." It is not a foreign word. It is not even the Syriac word for God. It is pure Arabic. (3)
Neither is Allah a Hebrew or Greek word for God as found in the Bible. Allah is a purely Arabic term used in reference to an Arabian deity.
Hasting's Encyclopedia of Religion and Ethics states:
"Allah" is a proper name, applicable only to their [Arab's] peculiar God. (4)
According to the Encyclopedia of Religion:
"Allah" is a pre-Islamic name...corresponding to the Babylonian Bel. (5)
For those people who find it hard to believe that Allah was a pagan name for a peculiar pagan Arabian deity in pre-Islamic times, the following citations may be helpful:
"Allah is found...in Arabic inscriptions prior to Islam (Encyclopedia Brittanica). (6)
The Arabs, before the time of Mohammed, accepted and worshipped, after a fashion, a supreme god called allah (Encyclopedia of Islam, ed. Houtsma). (7)
Allah was known to the pre-Islamic Arabs; he was one of the Meccan deities (Encyclopedia of Islam, ed. Gibb). (8)
Ilah...appears in pre-Islamic poetry....By frequency of usage, al-ilah was contracted to allah, frequently attested to in pre-Islamic poetry (Encyclopedia of Islam, ed. Lewis). (9)
The name Allah goes back before Muhammed (Encyclopedia of World Mythology and Legend). (10)
The origin of this (Allah) goes back to pre-Muslim times. Allah is not a common name meaning "God" (or a "god), and the Muslim must use another word or form if he wishes to indicate any other than his own peculiar deity (Encyclopedia of Religion and Ethics). (11)
....Caesar Farah in his book on Islam concludes his discussion of the pre-Islamic meaning of Allah by saying:
"There is no reason, therefore, to accept the idea that Allah passed to the Muslims from the Christians and Jews. (15)
According to Middle East scholar E.M. Wherry, whose translation of the Quran is still used today, in pre-Islamic times Allah-worship, as well as the worship of Ba-al, were both astral religions in that they involved the worship of the sun, the moon, and the stars. (16)
In Arabia, the sun god was viewed as a female goddess and the moon as the male god. As has been pointed out by many scholars such as Alfred Guilluame, the moon god was called by various names, one of which was Allah! (17)
The name Allah was used as the personal name of the moon god, in addition to other titles that could be given to him.
Allah, the moon god, was married to the sun goddess. Together they produced three goddesses who were called "the daughters of Allah." These three goddesses were called Al-Lat, Al-Uzza, and Manat.
The daughters of Allah, along with Allah and the sun goddess were viewed as "high" gods. That is, they were viewed as being at the top of the pantheon of Arabian deities.
....The Quraysh tribe into which Muhammad was born was particularly devoted to Allah, the moon god, and especially to Allah's three daughters, who were viewed as intercessors between the people and Allah.
The worship of the three goddesses, Al-Lat, Al-Uzza, and Manat, played a significant role in the worship at the the Kabah in Mecca. The first two daughters of Allah had names which were feminine forms of Allah.
The literal Arabic name of Muhammad's father was Abd-Allah. His uncle's name was Obied-Allah. These names reveal the personal devotion that Muhammad's pagan family had to the worship of Allah, the moon god.
....The worship of the moon god extended far beyond the Allah-worship in Arabia. The entire fertile cresent was involved in the worship of the moon.
This, in part, explains the early success of Islam among Arab groups that traditionallyhad worshiped the moon God.
The use of the crescent moon as the symbol for Islam which is placed on the flags of Islamic nations and on the top of mosques and minarets is a throwback to the days when Allah was worshiped as the moon god in Mecca.
While it may come as a surprise to many Christians who have wrongly assumed that Allah was simply another name for the God of the Bible, educated Muslims generally understand this point.
....The significance of the pre-Islamic source of the name Allah cannot be overestimated.
....The Qurans' concept of deity evolved out of the pre-Islamic pagan religion of Allah-worship. It is so uniquely Arab that it cannot be simply reduced to Jewish or Christian beliefs.(pages 47-53)
