Islam worships a Hindu God

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.
Allah was one of the deities in Kaaba long before Islam was founded. the word 'ALLAH' itself is Sanskrit. In Sanskrit language Allah, Akka and Amba are synonyms. They signify a goddess or mother. The term 'ALLAH' forms part of Sanskrit chants invoking goddess Durga, also known as Bhavani, Chandi and Mahishasurmardini. The Islamic word for God is., therefore, not an innovation but the ancient Sanskrit appellation retained and continued by Islam. Allah means mother or goddess and mother goddess.
The King Vikramaditya inscription was found on a gold dish hung inside the Kaaba shrine in Mecca, proving beyond doubt that the Arabian Peninsula formed a part of his Indian Empire. (Ref: page 315 of a volume known as 'Sayar-ul-Okul' treasured in the Makhtab-e-Sultania library in Istanbul, Turkey). King Vikrama's preachers had succeeded in spreading the Vedic Hindu sacred scriptures in Arabia and Arabs were once followers of the Indian Vedic way of life. The annual fair known as OKAJ which used to be held every year around the Kaaba temple in Mecca and the present annual hajj of the Muslims to the Kaaba is of earlier pre-Islamic congregation. . Even to this day ancient Siva emblems can be seen. It is the Shankara (Siva) stone that Muslim pilgrims reverently touch and kiss in the Kaaba.
Muslims shave their head and beard and don special sacred attire that consists of two seamless sheets of white cloth. One is to be worn round the waist and the other over the shoulders. Both these rites are remnants of the old Vedic practice of entering Hindu temples clean and with holy seamless white sheets. According to the Encyclopedia Britannica, the Kaaba has 360 idols. Traditional accounts mention that one of the deities among the 360 destroyed when the place was stormed was that of Saturn; another was of the Moon and yet another was one called Allah. That shows that in the Kaaba the Arabs worshipped the nine planets in pre-Islamic days. In India the practice of 'Navagraha' puja, that is worship of the nine planets, is still in vogue. Two of these nine are Saturn and Moon. In India the crescent moon is always painted across the forehead of the Siva symbol. Since that symbol was associated with the Siva emblem in Kaaba it came to be grafted on the flag of Islam.
Another Hindu tradition associated with the Kaaba is that of the sacred stream Ganga (sacred waters of the Ganges river). According to the Hindu tradition Ganga is also inseparable from the Shiva emblem as the crescent moon. Wherever there is a Siva emblem, Ganga must co-exist. True to that association a sacred fount exists near the Kaaba. Its water is held sacred because it has been traditionally regarded as Ganga since pre-Islamic times (Zam-Zam water)
