Chapter on the Divorce of a Missing Person
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 22
وَ رَوَى مُوسَى بْنُ بَكْرٍ عَنْ زُرَارَةَ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْمَرْأَةِ نُعِيَ إِلَيْهَا زَوْجُهَا فَاعْتَدَّتْ وَ تَزَوَّجَتْ فَجَاءَ زَوْجُهَا اَلْأَوَّلُ فَفَارَقَهَا وَ فَارَقَهَا اَلْآخَرُ كَمْ تَعْتَدُّ لِلنَّاسِ فَقَالَ "ثَلاَثَةَ قُرُوءٍ وَ إِنَّمَا يُسْتَبْرَأُ رَحِمُهَا بِثَلاَثَةِ قُرُوءٍ تُحِلُّهَا لِلنَّاسِ كُلِّهِمْ".
Musa ibn Bakr narrated from Zurara who said: I asked Abu Abdullah عليه السلام about a woman who was informed that her husband had passed away, so she observed her waiting period (iddah) and remarried. Then her first husband returned, leading both her first and second husbands to separate from her. I asked how long she should observe the waiting period for people (before remarrying). Imam عليه السلام said: "Three menstrual cycles (qur). Indeed, her womb is cleared after three menstrual cycles, which makes her lawful for all men."
