Are all those Muslim women all over the world who wear a hijab (a veil یا a scarf) much مزید devoted Muslims than those Muslim women who don't?

Have no idea but I think we should never judge somebody سے طرف کی their appearance . We might say that a hijabi is مزید devoted but who knows if a non hijabi prays 5 times daily and is مزید devoted to her religion and try to keep Almighty happy and constantly fears Allah مزید than a hijabi :)
