Four reasons Females Don't wear the Hijab:
--They feel they will not be "beautiful" with it on.
(If you are confident in your own skin doesn't matter if you are covered or uncovered.)
--They think it's "Optional" & not obligatory.
(In Surah Nisa, verses are stated why hijab is compulsory.)
--Society will not respect them.
(Society will never respect you regardless if you are good or bad, "Only God can judge you.")
--Some Mothers don't wear it, and don't mind if daughters don't cover the hair.
(Your mother will not join you in your grave, you have to answer for your own actions.)
