The team of scientists from New York’s Stony Brook University of Medicine, looked at patients with cardiac arrests in Europe and the US. They noted that those of the patients who were successfully resuscitated after their heart had stopped beating could recall the conversations around them between the healthcare personnel and were aware of their surroundings.
Study leader Dr. Sam Parnia said that the patients could describe in details what happened around them. He explained that the time death is declared is the one when the heart stops beating. As the heart stops beating, it stops pumping blood to the brain and slowly the brain begins to shut down, he explains. He added that this process of the brain shutting down slowly may take hours and the person may be dead during this time but aware of their surroundings.
The viewpoint of theologians
Dr. Mahmoud, one of the scholars of Al-Azhar, said: It is narrated that the Messenger Muhamed, used to call the dead by their names: Have you found what your Lord truly promised? The Muslims said: O Messenger of God, do you call upon a people who have died? He said: They hear, but they cannot answer me. The doctor believes that this is not the privacy of the Prophet, as the deceased is happy to visit his family to his grave.
The death of the prophets
Religious scholars unanimously agree that the bodies of all prophets don't disintegrate or wear out.
The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day. White blood cells, which are more independent, can keep going for almost three days.
During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).
The rate of autolytic spread throughout the body is dependent on the quantity of enzymes present—the dispersion in liver tissue, which is rich in these proteins, would take place much more rapidly than it would in lung tissue, which has a smaller reserve. This progression also depends on the amount of water present in a tissue. (The brain, being very high in water content, would degrade faster than, say, muscle tissue.)[\b] Autolytic spread, however, is most intimately tied to environmental temperature. In cold surroundings, the autolytic process slows down, while warm conditions speed up the progression. This is why people who have drowned in very cold water and are not recovered for an hour or so can, in some circumstances, be completely revived. The cold temperatures have slowed down the autolytic process to the point that no permanent damage has occurred in the tissues.

Untrue, a body is a body even of an enlightened, they also get cold, fever, fire will burn their bodies too. Don't listen to this false stories, what they mean is something else not body. But mind mind remains alive but mind has no body it will take new birth. There are ways for you to know who you were in past lives through hypnosis or meditation that is what he meant.
