Islam means submit to the GOD the creator of Mankind and the Universe. And I believe all the religion propagates the same and the peace would be in submitting to your God the creator of Mankind and the Universe.
Since Muhammad PBUH is the last Messenger sent by God to earth and Quran the latest revelation comparing to Judaism, Christianity and Hinduism.
A verse in Quran related to Abraham PBUH about throwing him in Fire and God's Miracle protected Abraham from fire is also available in Puranas, Bible and Tur (the books of Jesus and Moses).
Puranas also says do no worship Material Gods for material benefits. Do the Brahmins tell the same?
Though the older and newer religions have differences but the ultimate propagation is same. Submit to your God and that is Islam a common religion of all. Except some additional practices which Quran the book of creator of Mankind and Universe prohibits practices of involving deities and other objects with God.
But the good thing in India is people do not bother about other religions and freely practice whatever they like. Though it is idol worship, nudity, human sacrifices, Jogins (women bond in temples), sati, child marriages at the age of 3,4,5,6 and dowry. Nothing is stoppable, though there is law to protect individual rights and abolish old customs; people are free to follow whatever they choose is right.
