Death is a known and famous phenomenon. Everybody knows it, and every time and again people witness this fact. There is no a human being who does not know death or does not remember it. But death-related things belong completely to the unseen. They cannot be seen, felt, or compared.
It is worth noting here that it is Allah alone who gives life and causes death.
What is death?
What happens to people when they die?
How is their condition?
Death simply includes a heartbeat that stops beating, blood flow, and stagnation? Or something else?
After a person dies is it all over?
According to Islamic Aqeedah, this world is nothing but a test ground for man. It is just an opportunity to take an exam before they move to the land of main life and prove how their worth. Man is only acting in this world for the sake of the eternal world.
In Islam, the death of a person means that he has passed from this world to that world, moving from the provisional world to the eternal world. In the new and eternal world, the angels will welcome him and station him. They ask questions for them and point out a book of deeds to show them where they are worthy. Then they show him the place. The work begins with the grave.
Question of the grave
It is obligatory on every Muslim to believe that the dead should be questioned by the angels in the grave.
When a Muslim is questioned by two angels, Allah assist him with the help of a sublime word - he is would be able to give the testimony.
