Question Summary:
Hurmatul Musaharah Query

Question Detail:

URGENT!! I have read the establishment of harmah al musahara, and I am sure that I have committed this act with my step mother. Can repentance solve the issue or I need to go talk to my father and my step mother?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
The ruling and repercussions of Hurmah al-Musaharah are delicate, complicated, and harsh. Each case should be considered on an individual case-by-case basis. Thus, we advise you to send us a detailed account of the encounter between yourself and your step-mother before a ruling is issued.[1]
 
Nonetheless, you should engage yourself in constant Istighfar and Tawbah expressing remorse over your actions.
 
And Allah Ta’āla Knows Best
