Re: I believe in all Gods. Cos they're ONE.
Dunno what you mean by "All Gods". However Quran is there to help you. Here is a quotation from Sura Baqarah.
**[Muslims] believe in Allah, AND (All of) His Angels, AND (All of) His books, AND (All of) His Messengers,
AND
They do not try to make one of them [Messengers, Books, or Angels] superior over the other.
(portions from 2:285)
**
So yes, we believe in Mohammad, Jesus, Moses and ALL other Messengers.
We do not try to prove that Jesus was superior to the Moses or Mohammad and conversely Mohammad was any superior to the Jesus or Moses.
Similarly we believe in Bible, Quran, Torah and all other books. We do not try to prove that one of these books is any superior to the other.
Based on what I hear and read about Hinduism, they were blessed by the divine message as well. So the respect of Hindu religion is of utmost importance to a Muslim.
