You wrote: Yes, indeed seperation is a must! and the compensation is to bear her burden till she decides to move on. ARE YOU REFERRING TO MULTIPLE WIVES OF A MAN?
By the way isn't it unfair not to include woman's choice in all this? ABSOLUTELY YES, WIFE'S CHOICES ARE NO LESS IMPORTANT AFTER THE DIVINE INJNCTIONS.
Just curious to know, will she be willing to stay with the man knowing what she has done is against Allah SWT Will and against His laws? IF IT HAS BEEN A MARRIAGE AMONG THE FORBIDDEN RELATIVES (MAHRAMS), AREN'T BOTH AWARE OF THE WRONGDOING BEFOREHAND?
Should she keep on living with her so called husband? IN WHAT SITUATION?
