All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
It is not permissible for a Muslim (male or female) to undertake doing something until he/she knows whether it is Lawful or forbidden because the knowledge of what is forbidden and what is allowed is among the individual obligations.
However, if a Muslim does not know whether something is Lawful or forbidden, then he/she is obliged to ask the scholars. If the person who informed him/her that the matter which he/she asked about is forbidden was one of the scholars, then he/she is obliged to act according to what the scholar said. Allaah Says (what means): {…so ask the people of the message if you do not know.}[Quran 16:43]
Allaah Knows best.
