Evolution of the Concept of Death.

The definition of death remains unresolved. To define death, one has to define the characteristics of a living person and to confirm whether an individual with brain death fulfils any of these characteristics. Although the concept of irreversible cessation of brain function is clear, controversy remains on the treatment of individuals with brain death and beating hearts. An individual with brain death but a beating heart is not breathing on his own and is dependent on medications and machines to maintain respiration, heartbeat, and blood pressure. Muslim scholars remain divided over the issue of whether death also means irreversible cessation of brain function. Questions remain on when it is permissible to remove vital organs for organ transplant. Groups have advocated for uniformity in law and medical practice on the definition of brain death.
