1) Before answering to your question, answer mine, if Hinduism is a Universal Religion, why no Avatar is born outside India ??? All your 330 Million Gods, Born, Lived and Died in India.. Do you mean to say that Hinduism is limited to the Borders of India ?? If it is true then why Vishnu is called Jagannath....
2) Now the Direct answer, it is clearly mentioned in the Koran that, there are Prophets send for all Civilizations to tell the Message of One God to every corner of the Globe..
3) Muslim Priests beleive that there are 1,42,000 Prophets till date send to various parts of the World for telling the Message to People..
4) Some Schools of Islam beleive that Shri Ram, Krishna are the Prophets of One God.. and they put forward the Truth, but People like you have Misinterpreted Vedas and started beleiving in the Creations and Forgeting about the Creator..
Hope it answers, if you have more doubts let us debate, I am fully loaded to deleiver...
