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. In Arabia, the sun god was viewed as a female goddess and the moon as the male god. God in Arabic is Elah. Allah means Curse in Hebrew. 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.

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. “Along with Allah, however, they worshipped a host of lesser gods and “daughters of Al-lah” The pagan Arabs worshipped the Moon-god Allah by praying toward Mecca several times a day; making a pilgrimage to Mecca; running around the temple of the Moon-god called the Kabah; kissing the black stone; killing an animal in sacrifice to the Moon-god; throwing stones at the devil; fasting for the month which begins and ends with the crescent moon; giving alms to the poor, etc. The Muslim’s claim that Allah is the God of the Bible and that Islam arose from the religion of the prophets and apostles is refuted by solid, overwhelming archeological evidence.

Islam is nothing more than a revival of the ancient Moon-god cult. It has taken the symbols, the rites, the ceremonies, and even the name of its god from the ancient pagan religion of the Moon-god. As such, it is sheer idolatry and must be rejected by all those who follow the Torah and Gospel. Allah is sin.
Often depicted as a wise old man with a long beard, the moon god Sin was one of the most important Babylonian gods. His main temples were situated at Ur and Harran. The moon god “sin” was elevated to the top of the Babylonian pantheon by Nabu-na’id (Nabonidus) in an effort to make Babylonian religion more acceptable to subjects like the Arabians and Arameans. The Arabians esteemed the moon god, but had more difficulty identifying with Marduk, the supreme Babylonian deity associated primarily with the city of Babylon. The god Sin, “The Controller of the Night,” had the crescent moon as his emblem, and the lunar-based calendar, which became the primary religious symbols of Islam, was worshiped in Arabia as AI-Ilah. Mecca became the center of all pagan religions of Arabia before Mohammed. AI-Ilah, the Moon God, was the “Lord of the Ka’aba” (“cube”) which held the pagan black rock idol and was formerly the center of pagan worship, ruling over 360 idols.
Lucrative trade routes resulted in meca. Pagans who lived in Saudi Arabia before Muhammad was born worshiped toward Mecca because Mecca is where their idols were located.
Because this pagan worship centered on Mecca was so widespread, a rapid acceptance of Muhammad’s new religion was possible. Thus, Islam is a previously heathen religion modified into a monotheistic form by discarding all the other pagan gods except for Al-Ilah. Al-Ilah simply became Al-lah over time.
Islam still worships a black stone idol as well as Al-Ilah the sin god. Al-Ilah was the pagan Lord of the Ka’aba when Muhammad made up Islam, he just dropped the “i” and name has been simplified to Allah.
The Ka’aba black cube in Mecca houses the occult black rock of Allah. It is of course still the center of pagan Islamic worship today. The requirement for a Holy Pilgrimage (hajj) to Mecca, in order to circle the Ka’aba. The site of the black stone idol is to be circled 7 times and kissed. Pilgrims then run to the Wadi Mina to throw stones at the “devil”. Islam incorporates beliefs in jinns which are demons genies, fairies.
They believe in spells, magic stones, fetishes, and animistic beliefs (spirits living in inanimate objects). See: Suras 55; 72; 113, 114. These pagan rites are practiced in Islam today.
