It is this same issue - meaning the focus upon Allah (SwT) and turning away from the material world which leaves a deep effect on our souls. A person must truly believe that at any moment, one is in the grips of danger. For example, pay attention to the heart which makes the blood reach all the parts of the body. The heart is the centre from which the blood is distributed, however it does not take its own nourishment from the blood which is inside itself.

In reality, the heart considers itself as equal to all the other parts of the body (and thus waits for the blood to be distributed to it). Sometimes the walls of the secondary blood veins become very narrow or develop a clot in them - and as it is known, blood can clot very easily.

As soon as the blood comes out of the veins, we see that there is something inside it which makes it clot and sometimes it can also be seen that the agents which make up the blood can become contaminated and thus the blood clots right there in the veins and through this clot of the blood is so small - maybe one millimeter in size - however it takes over the channels in the blood vessels and thus, the blood can no longer reach to the heart.

When this occurs, then after a few minutes the heart will stop working and this is what is known as a heart attack. When a specialist in this field (Physiologist) explains this to a person, that individual will develop fear since he knows that it is possible that he could die at any instant. Sometimes he may even plunge himself into doubts and the evil whisperings may overtake him.

The vessels that pass through the brain are much thinner than those which are contained in the petals of a flower and if there was to be any excess pressure on one of these, and if one of these blood veins was to burst, then with that blood spilling inside the brain, it is very well possible that the person could die. In addition, it is possible that someone - due to having one bite of food to eat - could also die.

When a person is eating, if a small piece of food or something else was to enter into the air-pipe which controls one's breathing, then the only way that this can come out is through coughing it out. However if the morsel of food or thing that went down the pipe was large, then it would stay in the pipe and there is nothing that could bring it out - except for death. Thus in summary, dying is something that is simple and can come about very easily.
