Is it permissible for a Muslim man to marry a non-Muslim woman who is still married to a non-Muslim man? Is there an ‘idda period for her when she separates from her non-Muslim husband? What is the period of that ‘idda? Is it permissible to have sexual relations with her during the time when she is in the ‘idda from her non-Muslim husband? If she embraces Islam, how long will her ‘idda be, if she intends to marry a Muslim man?
