What is the ruling on the marriage of third-gender individuals and their gender transformation surgery, and who is to wash and shroud them?

An intersex person (khuntha) has two possible situations: either their true gender (male or female) becomes clear, in which case they are treated according to the gender that has been revealed; or they remain ambiguous (mushkil), in which case they are treated with the stricter (precautionary) ruling. It is permissible for an ambiguous intersex person to undergo a gender reassignment surgery if physicians determine it aligns more closely with their characteristics, and a physician is permitted to perform it in this case; otherwise, it is not. As for an intersex person whose gender has been clarified, it is not permissible for them to change to another gender, but it is permissible to remove characteristics that do not belong to their gender. Marriage to an intersex person is permissible if their gender becomes clear or if they undergo gender reassignment surgery, provided its conditions are met; otherwise, it is not permissible. In congregational prayer behind an ambiguous intersex person, the stricter ruling applies, but if their gender becomes clear, they are treated accordingly.
