What is the method for calculating the 'iddah (waiting period) of an adulteress if there was multiple intercourse or multiple perpetrators? And does the 'iddah begin from the last act of intercourse or from the last perpetrator? What is the ruling on one who did not know about the obligation of the 'iddah until a year after her repentance? And is the 'iddah invalidated merely by leaving the house, or by seeing the one who committed adultery with her, or by sexual fantasies? And is she obligated not to marry and not to leave the house?

The adulterer is obligated to perform sincere repentance. The validity of repentance is not affected by the 'iddah (waiting period). The 'iddah begins from the last act of intercourse and does not multiply with multiple acts of intercourse or multiple perpetrators in adultery. It is a short period and usually ends after one year from the last act of intercourse. Leaving the house during the 'iddah, or thinking about sexual fantasies, or seeing relatives or the person with whom adultery was committed, does not affect the 'iddah. The woman should abandon obsessive thoughts and hasten to marry due to the tremendous benefits therein. She is permitted to seek husbands with the assistance of trustworthy individuals.
