Dear Kafir Sahab, we Indians are eager to own-up the parentship of every thing on earth! We would even claim that Nuclear Bombs are the Brahmastras described in Mahabharata. There could be some similarities in the method of worship of the population the world over as it is believed that the mankind originated in Africa and spread to different parts of the world in due course of time. Many of our epics are the oral traditions of the ancient civilizations.
The Arab traditions and those propagated by The Prophet (Mohammed) are entirely different from those prevailing in the ancient India. I doubt whether Prophet Mohammed was even aware of a country called India (btw the India of that time consisted of many princely states at war with each other).
Hinduism is not a religion in its strict sence. Our constitution defines all those who are not followers of Islam, christianity, Judaism and Zorashtrainism as Hindus. The same is a coglomeration of various beliefs and even by that defnition atheists like me are also Hindus.
