I have concluded my marriage contract at a Sharia court; however, one day I was talking to my fiancée over the phone and she got on my nerves leading me to utter one divorce. This is knowing that I can`t tell my her father because he is very strict and will not accept that at all. What is the best course of action that I should pursue in this situation?
All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon Prophet Mohammad and upon all his family and companions.
