The Ruling on Donating Blood and Human Organs, Whether from a Living or Dead Person

Question:
Is it permissible to donate blood or human organs, whether from a living or dead person? Please issue a ruling for us. May Allah reward you with good.

Answer:
As for donating blood when there is a dire necessity for it, there is nothing wrong with it and no blame on one for doing so. A decision has been issued by the Council of Senior Scholars to this effect, due to the great public benefit it offers, without any harm, in cases of dire necessity to save a patient, just as it is permissible to eat carrion.
As for donating organs: there is scholarly disagreement among the scholars on this. Some scholars of the present era have permitted it, while others have prohibited it. In my view, I am hesitant about it, and I am not among those who permit it. I am hesitant about its permissibility.
Donating a kidney, a heart, or other organs has been permitted by some scholars, who said that it falls under the category of excellence in worship, the category of voluntary charity, and the category of generosity.
Others have prohibited it, saying that it is a form of likening Allah to creation, a form of danger, and that a person has no authority over his own self or his organs. He might act in a way that harms him, leading to his death.
Some scholars have been hesitant about this, and I am among those who are hesitant regarding the permissibility of this.
