Primary text
If a non-Muslim divorces his wife three times and then remarries her, and subsequently both convert to Islam, they do not affirm that marriage, and they do not inherit from each other. Similarly, if one of them dies before they both convert, they do not inherit from each other. This is the opinion of all scholars.
