Rav Aviner, a leading mizrachi rav, has many interesting questions addressed to him and often comes up with some of the most interesting rabbinic responses of our time.
Here’s one of his questions of the week…
Q: If a woman was married to two different men during her lifetime, who will she be with after the Resurrection of the Dead?
A: There is an answer to this question in the book "Piskei Teshuvah" of Ha-Rav Avraham Pitrakovsky (#124). He quoted the book "Shut Matzav Ha-Yashar" on the Zohar that there was a young woman who was married to a wonderful man who died at a relatively young age. The young woman did not want to marry again. She said, "Why should I get married to someone else? During the Resurrection of the Dead I will be married to my second husband, and my first husband is dearer to me than anything. I prefer to remain a widow all of my life and then be married to my true soul-mate."
There is a similar question in the book "Ha-Techiya Ve-Ha-Pedut" (question #6) of Ha-Rav Sa'adia Gaon: how will I find my wife during the Resurrection of the Dead? Ha-Rav Sa'adia did not want to answer since it is forbidden to answer a halachic question before someone who is greater than him in wisdom. Since this is a question of the Resurrection of the Dead, Moshe Rabbenu will be there and it is therefore forbidden for me to answer. If there are questions that arise now - what can we do? We have to answer them. Questions that have to do with the future, however, we leave for Moshe Rabbenu and the other prophets.
It therefore seems that the question in "Shut Matzav Ha-Yashar" cannot be answered, but this was before the Zohar was revealed. After the Zohar was revealed, our question was answered.
