Visiting shrines of Muslim saints is a common practice in India. These saints may or may not be Shia but there followers are mostly Sunni specially Barelvi Sunnis. Are we allowed to visit these shrines? The shrine at Ajmer and Dewa is an example.

Before you visit a shrine you must research about the person buried in it to make sure he was righteous and that he was on the right path. Do research then based on your research visit those shrines. If the person was not on the right path, you should not visit his shrine.
