A temple of the Moon-god has been excavated in Ur by Sir Leonard Woolley. He dug up many examples of moon worship in Ur and these are displayed in the British Museum to this day. Harran was likewise noted for its devotion to the Moon-god. In the 1950's a major temple to the Moon-god was excavated at Hazer in Palestine. Two idols of the moon god were found. Each was a stature of a man sitting upon a throne with a crescent moon carved on his chest .

The accompanying inscriptions make it clear that these were idols of the Moon-god. Several smaller statues were also found which were identified by their inscriptions as the "daughters" of the Moon-god. What about Arabia? As pointed out by Prof. Coon, "Muslims are notoriously loath to preserve traditions of earlier paganism and like to garble what pre-Islamic history they permit to survive in anachronistic terms."

During the nineteenth century, Amaud, Halevy and Glaser went to Southern Arabia and dug up thousands of Sabean, Minaean, and Qatabanian inscriptions which were subsequently translated. In the 1940's, the archeologists G. Caton Thompson and Carleton S. Coon made some amazing discoveries in Arabia. During the 1950's, Wendell Phillips, W.F. Albright, Richard Bower and others excavated sites at Qataban, Timna, and Marib (the ancient capital of Sheba).

Thousands of inscriptions from walls and rocks in Northern Arabia have also been collected. Reliefs and votive bowls used in worship of the "daughters of Allah" have also been discovered. The three daughters, al-Lat, al-Uzza and Manat are sometimes depicted together with Allah the Moon-god represented by a crescent moon above them. The archeological evidence demonstrates that the dominant religion of Arabia was the cult of the Moon-god.

In Old Testament times, Nabonidus (555-539 BC), the last king of Babylon, built Tayma, Arabia as a center of Moon-god worship. Segall stated, "South Arabia's stellar religion has always been dominated by the Moon-god in various variations." Many scholars have also noticed that the Moon-god's name "Sin" is a part of such Arabic words as "Sinai," the "wilderness of Sin," etc. When the popularity of the Moon-god waned elsewhere, the Arabs remained true to their conviction that the Moon-god was the greatest of all gods. While they worshipped 360 gods at the Kabah in Mecca, the Moon-god was the chief deity. Mecca was in fact built as a shrine for the Moon-god.

This is what made it the most sacred site of Arabian paganism. In 1944, G. Caton Thompson revealed in her book, The Tombs and Moon Temple of Hureidha, that she had uncovered a temple of the Moon-god in southern Arabia. The symbols of the crescent moon and no less than twenty-one inscriptions with the name Sin were found in this temple. An idol which may be the Moon-god himself was also discovered. This was later confirmed by other well-known archeologists.

The evidence reveals that the temple of the Moon-god was active even in the Christian era. Evidence gathered from both North and South Arabia demonstrate that Moon-god worship was clearly active even in Muhammad's day and was still the dominant cult. According to numerous inscriptions, while the name of the Moon-god was Sin, his title was al-ilah, i.e. "the deity," meaning that he was the chief or high god among the gods.

As Coon pointed out, "The god Il or Ilah was originally a phase of the Moon God." The Moon-god was called al-ilah, i.e. the god, which was shortened to Allah in pre-Islamic times. The pagan Arabs even used Allah in the names they gave to their children. For example, both Muhammad's father and uncle had Allah as part of their names.

The fact that they were given such names by their pagan parents proves that Allah was the title for the Moon-god even in Muhammad's day. Prof. Coon goes on to say, "Similarly, under Mohammed's tutelage, the relatively anonymous Ilah, became Al-Ilah, The God, or Allah, the Supreme Being."

This fact answers the questions, "Why is Allah never defined in the Qur'an? Why did Muhammad assume that the pagan Arabs already knew who Allah was?" Muhammad was raised in the religion of the Moon-god Allah. But he went one step further than his fellow pagan Arabs. While they believed that Allah, i.e. the Moon-god, was the greatest of all gods and the supreme deity in a pantheon of deities, Muhammad decided that Allah was not only the greatest god but the only god.

In effect he said, "Look, you already believe that the Moon-god Allah is the greatest of all gods. All I want you to do is to accept that the idea that he is the only god. I am not taking away the Allah you already worship. I am only taking away his wife and his daughters and all the other gods." This is seen from the fact that the first point of the Muslim creed is not, "Allah is great" but "Allah is the greatest," i.e., he is the greatest among the gods. Why would Muhammad say that Allah is the "greatest" except in a polytheistic context?

The Arabic word is used to contrast the greater from the lesser. That this is true is seen from the fact that the pagan Arabs never accused Muhammad of preaching a different Allah than the one they already worshipped. This "Allah" was the Moon-god according to the archeological evidence. Muhammad thus attempted to have it both ways. To the pagans, he said that he still believed in the Moon-god Allah. To the Jews and the Christians, he said that Allah was their God too. But both the Jews and the Christians knew better and that is why they rejected his god Allah as a false god.

Al-Kindi, one of the early Christian apologists against Islam, pointed out that Islam and its god Allah did not come from the Bible but from the paganism of the Sabeans. They did not worship the God of the Bible but the Moon-god and his daughters al-Uzza, al-Lat and Manat. Dr. Newman concludes his study of the early Christian-Muslim debates by stating, "Islam proved itself to be...a separate and antagonistic religion which had sprung up from idolatry." Islamic scholar Caesar Farah concluded "There is no reason, therefore, to accept the idea that Allah passed to the Muslims from the Christians and Jews."
