What comes after death?
When man dies, his soul vanishes and then his body is perished and decayed because it is a form of physical elements so when this abstract fact which is the spirit and what its attaches leave it, its physical elements soon decay and return again to its origin which is earth, as God says:
20:55. “From the (earth) did We create you, and into it shall We return you, and from it shall We bring you out once again.”
The spirit never dies or gets extinct but it goes to a spiritual world called the interval world, God says about this:
23:100. “Before them is a Partition till the Day they are raised up.”
This interval is the partition between two things, so the partition world is the abstract spiritual world between this life and the hereafter. Spirits meet there and lead an interval abstract life because after spirits get rid of the body which is intense and thick because it is from the elements of the earth, now there is only the spirit and its attachments which are from the world of light which is mild.
Everything in the world of partition is mild and can see us but we can’t see them. We can only realize facts about this world through revelation and prophecy or by the science of vision or apocalypse or by truthful dreams of righteous people.
This world continues until this life gets to an end and no creatures will be there, then everything starts to get ready for resurrection and questioning at the hereafter.
The hereafter, the interval and the Day of Judgment are all unseen and hidden worlds that believers who follow prophets and apostles must believe in them, God says about them:
2:2 and 3. “This is the Book; in it is guidance sure, without doubt, to those who fear God. Who believe in the Unseen"
