Persistent Vegetative State

Neurologists consider the human beings who are in vegetative state that is:
the person has lost the ability to interact with surroundings or other persons
May have some reflex movements preserved
May have lost the ability to eat or drink and would only maintain nutrition and hydration provided and maintained by others.
They call it persistent or permanent when this state goes on without improvement for three months.
Most people became aware of this condition a couple of years ago when in Terry Chiavo, a young woman who had been in that state for years and her husband wanted to discontinue nutrition and hydration whereas her parents wanted to continue.
A recent news from Italy about a woman who developed that state at age 17 and dies at age 38 while her Pastors and Vatican were teaching her parents to maintain her and NOT take the tubes out. Here it should be noted that Roman Catholic teaching insists on maintaining.
I was wondering the poor girl had more "Life" on tubes (21 years) than her real active life (17 years).
Such patients will die from dehydration within a couple of weeks if left alone and they do not feel hungry or thirsty as far as can be ascertained. There are tests that may indicate who is more likely to pull through such vegetative state and who is not likely to do so.
But on the whole we still have problems that have been created by our advanced technology. Philosophical and moral teachings without religious guidance are unable to help here and in some cases the religious guidance does not help.
I have therefore a plea to the Islamic scholars to get together and make statements for guidance of the Muslim population of this world on all these matters pertaining to technological advancements or indeed produced by them. Muslims need a scholars forum (muftees of all schools of thought) expressly for this purpose, active and ongoing and we need it today.
