Thank you for this informative thread
I think the problem for us now is that our mind is not able to understand how wonderful Jannah will be even if our husbands will have more than one wife. I also think now I didn't want to share my dear husband not even in Jannah but this are our feelings from here from this world. We will not be jealous in Jannah and what eases my mind is that Allah will satisfy the wishes of every single one of us no matter if man or woman.
