Where are the souls after death? For a believer their grave is expanded 70 x 70 subhanAllah. There is a light that comes in to the grave. The angel come to them and show them their garden in paradise two times a day. The believer asks the angels can they go back to their family to tell them how they are doing. The angels tell them to sleep now.
There is no doubt there is a connection with the soul and this world. Once a person is buried their grave is no longer limited to the dimensions of this world and the soul is no longer limited by the body.
We pray that all our souls be the souls which roam around the gardens of jannah eating from its fruit.
