Is it permissible for a wife to donate one of her kidneys to her husband?

The questioner : The questioner:The questioner : He asks: Is it permissible for a wife to donate one of her kidneys to her husband?

The Shaykh : It is not permissible. This is a bad religious innovation in the present age. We often hear some muftis or counselors, or the like, issuing fatwas that it is permissible. While we respect the opinions of these people, who base their fatwas on some degree of independent legal reasoning (ijtihad), we see that this is a grave error. First, they find no scriptural basis for their position other than mere derivation and ijtihad. However, this ijtihad and derivation overlooks some other texts that must be considered when issuing such a fatwa. Donating a kidney is either from a living person, which is the common case and the subject of the question and answer, or from a person who died recently, where the kidneys are still considered alive by doctors and can be used for a living person, either both or one. In the first case, that is, when one of the kidneys is extracted from a living person as mentioned in the question, the donor is exposed to harm, if not death. I will illustrate this to clarify the answer. If we asked these doctors and those muftis: "Do you guarantee, O mufti, based on the opinion of the Muslim doctor, that this man who will remain with one kidney will not be exposed to its corruption or illness after the removal of its twin, even if it is not immediately after, but after a very long time?" The answer, in my belief, and we have a doctor here who makes things easy, so we can benefit from his answer, I think the answer will be: It is not possible to guarantee the safety of this kidney after its twin is extracted. So here, first, the man who donates one of his kidneys is exposed to harm.
