There is a big debate going on in the internet as to whether Kaaba was initially a Shiva temple. The following are arguments from the side of Hindus who support this theory.
- Kaaba is derived from Kaabalishwara - The name of Shiva after he took crescent moon on his head. Crescent moon in the symbol of Islam.
- The stone that Haj pilgrims embrace is very similar or identical to Yoni of the Shivalinga. They also claim that the Shivlinga itself was removed and inserted in the SE corner of Kaaba.
- Practices like Circumambulation of the Kaaba 7 times which is similar to Vedic practice of Circumambulating Pradana Shtalas in temples.
- Inscriptions praising Emperor Vikramadithya in the Makhtab-e-Sultania library in Turkey which supposedly proves Vedic influence in Middle-East.
- Long standing trade connection between Kerala and Arabia.
- The first follower of Islam after the prophet, Malik Deenar came to Kerala and performed conversion of King Cheramal Perumal to Islam.
- Pagan Arab Priests of Kaaba and their Namboodhiri Brahmin ancestry.
- There is Triad of Godesses in pre-islamic Arabia (Al-Uzza,Al-Lat and Menat) just like Saraswati/Parvati/Lakshmi.
- The remains of Medein Saleh are said to have contained multi-armed idols.
Is there any truth to the above claims and many other similar claims in this regard?
