Life Support?

If, God forbid, you are in a terrible accident, and you can survive only by life support ( breathing tube, feeding tube, etc.) is it haram for your family members to take you off support and you die? Or should they keep you on life support because their is a tiny chance you may recover brain function and because only Allah can decide when you die? Any Islamic ruling on this matter?

Stopping life support in this case is considered as passive euthanasia.

So, you can search some references about passive euthanasia in Islam.
