Re: jannat
The men's wife will remain as wife along with other HOORS, and will be very happy. Because there will be no worldly jealousies like in this world. They will be leaving together very very happy.
Regarding the women who have no husbands, I am not sure..... But they may be attached OR married to other Ahle Jannat men....WALLAH-O-AÁLAM......Allah Knows the Best....
