Asrar, Hindu donot believe in conversion. We say that every way of worship is acceptable. God is one and to reach to it are mny path and all are equally good.
It is our strength as well as weakness. It is a great strength when one is living in a civilised society but it is a great weakness when one is encountering a intolerant religion like Islam.
Islam doesnot allow apostate( change of Faith) and punishment for the same is DEATH. Now there is lot of awakening among Hindus and in future you will see the home coming.
