HINDU GODESS OF PREISLAMIC ARABIA :

In pure scientific study about the Historical Muhammad raises basic questions concerning the prophet's role as a moral paragon; the sources of Islamic law; and the God-given nature of the Koran. The scientists even doubt the existence of Muhammad. Scientists say that the Koran is a not a product of Muhammad or even of Arabia, but a collection of materials stitched together to meet the needs of a later age. There was no Islam until two or three hundred years after the traditional version at around 830CE. The Arab tribesmen who conquered in the seventh century vast territory were not Moslems, but were persons who worshiped idols and are scientists call them pagans.
Even though Prophet Muhammad was born in the full light of history the earliest document date about a century and a half after his death. Not only does this long lapse of time cast doubt on their accuracy, but internal evidence strongly suggests the Arabic sources were composed in the context of intense partisan quarrels over the prophet's life. The earliest sources like papyri, inscriptions, and coins on the prophet's life, contradict the standard biography.
An inscription and a Greek account fix Muhammad's birth in 552, not 570. Muhammad's career took place not in Mecca but hundreds of kilometers to the north. Yehuda Nevo. The classical Arabic language was developed not in today's Saudi Arabia but in the Levant.
Long before Islam came in to existence, Kaaba, in Mecca in Saudi Arabia was a pilgrimage site. The word Kaaba might have come from the Tamil Language which originated around 1700BC. In Tamil Nadu Kabaalishwaran temple is Lord Shiva’s temple and Kabaali refers to Lord Shiva. The black stone at Kaaba is held sacred and holy in Islam and is called "Hajre Aswad" from the Sanskrit word Sanghey Ashweta or Non-white stone. The Shiva Lingam is also called Sanghey Ashweta. So what is in Kaaba could be the same what Hindus worship.
The pedestal Maqam-E-Ibrahim at the centre of the Kaaba is octagonal in shape. In Hinduism, the pedestal of Brahma the creator is also octagonal in shape. Muslim pilgrims visiting the Kaaba temple go around it seven times. In no other mosque does the circumambulation prevail. Hindus invariably circumambulate or Pradakshina, around their deities. This is yet another proof that the Kaaba shrine is a pre-Islamic. In Shiva temples Hindus always practice circumambulation or Pradakshina. Just as in Hinduism, the custom of circumambulation by muslim pilgrims around the entire Kaaba building seven times shows that the claim that in Islam they don’t worship stones is not true
