Are human organ transplants permissible by Islamic law? Thank you.

Organ transplantation operations fall into two categories: The first is transplanting an organ or part of it from one place to another within the same person. This is permissible with three conditions: dire necessity, assurance of no threat to life, and a high probability of success. The second category is transplanting an organ from one person to another. Its first scenario is when the donor is deceased. Transplantation is permissible if the recipient's life is in danger or if they have lost a sense, provided there is a high probability of success and the deceased's will permits it, or the heirs give permission. Its second scenario is when the donor is alive. This is permissible without compensation for a Muslim in dire need, provided there is a high probability of the operation's success and no harm to the donor. However, it is not permissible to donate an organ that is essential for life or whose loss would lead to the cessation of a basic function.

General considerations must be observed: It is not permissible to sell organs, nor is it permissible to transplant reproductive organs. It is not permissible to transplant organs from a brain-dead person unless their vital functions have ceased and the signs of lawful death are apparent. The donor must be an adult and of sound mind. It is permissible to utilize a part of an organ removed due to a medical condition for another person.
