Second: It is permissible to transfer an organ from one human body to another when that organ regenerates naturally—such as blood or skin—provided that the donor is fully competent in law and all Sharʿī conditions are satisfied.

Third: It is permissible to make use of a portion of an organ that has been surgically removed for medical reasons by transplanting it to another person; for example, transplanting the cornea from an eye that has been removed on medical grounds.

Fourth: It is forbidden to transplant an organ on which life itself depends—such as the heart—from a living person to another.

Fifth: It is forbidden to remove from a living person an organ whose loss disables a basic bodily function, even if survival itself does not hinge on that function—such as removing both corneas. If the removal would disable only part of a basic function, the matter remains open to further study, as will be discussed in paragraph eight.

Sixth: It is permissible to transplant an organ from a deceased person to a living person whose life, or whose essential bodily function, depends on it, on condition that the deceased had consented during life or that his heirs consent after his death. If the deceased is unidentified or has no heirs, the approval of the Muslim authority suffices.

Seventh: It must be noted that the permissibility of transplantation in the aforementioned cases is contingent on the organ not being sold, for under no circumstances may human organs be treated as commercial property. As for the recipient offering money—whether out of necessity to secure the required organ or as a gratuity and token of appreciation—this is a matter for juristic discretion and further consideration.

Eighth: Any situation other than the cases described above that falls within the scope of this topic remains under study. It should be presented for examination at a future session in light of medical data and Sharʿī rulings. Allah knows best.
