While all of these rights and responsibilities are specified in Islam, they are not always adhered to in some places and during some periods of time. In the diverse Muslim world, local cultural influences are sometimes confused with Islamic practice.
It's important to differentiate between the teachings of the faith and the practices of some people who claim to practice it. If a practice is truly based in Islamic teaching, one will be able to research it in authentic sources of Islamic knowledge. By the same token, one must understand that our own backgrounds and experiences may cause us to have different interpretations of the same practice. While we may see something as outdated or conservative, the people who actually believe in and practice it see things in an entirely different light. We must all constantly seek knowledge to aid in our understanding.
