Is It Permissible to Turn Off Life Support When a Person Is Considered Medically Dead?
Question
As-salamu alaykum,
Is it permissible to turn off the life support system of a person who is thought to be dead, although some organs may still be functioning?
Answer
Alhamdulillah, wassalatu wassalamu ala rasulillah, wa ala alihi wa sahbihi ajmain.
This question involves the definition of death in Sharia, the ruling on medical life support, and the distinction between allowing death to take its course and actively causing death.
1. The Shar‘i Context
Islam places the highest sanctity on human life. It is strictly prohibited to intentionally end a life. However, Sharia also does not obligate the continuation of artificial means when death has already occurred in a legally recognized sense.
Allah says:
“And do not kill the soul which Allah has forbidden, except by right.”
Surat al Isra 17:33
At the same time, Sharia does not require futile medical intervention when death is established.
2. What Is Considered Death in Sharia
Classical jurists defined death as the departure of the soul, which is known by its signs. In modern medicine, scholars addressed how this is identified.
Many contemporary scholars and fatwa councils recognize two valid indicators of death:
- Complete and irreversible cessation of the heart and breathing, or
- Complete and irreversible cessation of all brain function, including the brain stem
If qualified, trustworthy physicians determine that brain death has occurred with certainty and irreversibility, then the person is legally considered dead, even if machines keep some organs functioning artificially.
In such a case, the functioning of organs is due to machines, not life itself.
3. Ruling on Turning Off Life Support
If death has been medically and legally confirmed by reliable specialists, then:
- Turning off life support is permissible
- It is not considered killing
- It is allowing the body to follow its natural course after death has already occurred
However, if the person is:
- Still alive
- Not brain-dead
- Or there is reasonable doubt about irreversibility
then turning off life support is not permitted, because it would directly lead to death.
4. Who Decides
The determination of death is not made by family members alone, nor by financial or emotional pressure.
It must be based on:
- The assessment of multiple qualified physicians
- Medical certainty of irreversibility
- Absence of reasonable disagreement among specialists
Once this is established, the Sharia ruling follows the medical reality.
5. Relevant Usul Principles
اليقين لا يزول بالشك
Certainty is not removed by doubt.
Life is presumed until death is established with certainty.
الحكم يدور مع علته وجودا وعدما
A ruling follows its effective cause, existing when it exists and ending when it ends.
When life no longer exists, the ruling requiring preservation of life no longer applies and Maintaining machines with no benefit after death constitutes harm without purpose.
Final Ruling
If a person has been medically and irreversibly declared dead, including confirmed brain death, then it is permissible to turn off life support, even if some organs continue to function due to machines.
This is not considered killing, but rather allowing death to take its course after life has ended.
However, if death has not been conclusively established, then turning off life support is not permissible.
Such decisions must be based on reliable medical determination, not assumption or pressure.
And Allah knows best.
