Dear Friend, To give simple answer for all above questions. please kindly surf google videos for Zakir Naik on his talks on Islam and Hinduasim. you will be surprised to know how Puranas, Vedas and all holy scriptures mention about prophet Mohammed (peace and blessings be upon him). I will not use the term Hindus... because it basically came from persion word and it has entirely different meaning. browse google videos to remove differences....
