Women using black dye on their hands
Question

                Is it permissible for women to draw on their hands using a black dye? .
Praise be to Allah.
    There is nothing wrong with using the black dye that is 
    called dooj, but if the dooj has any substance that prevents the water from 
    reaching the skin, it must be removed when doing ghusl from janaabah or 
    following menses and nifaas, and when doing wudoo’. 

    And Allaah is the Source of strength. May Allaah send 
    blessings and peace upon our Prophet Muhammad and his family and 
    companions.
