Is a mother's refusal to donate a kidney from one of her children due to psychological factors considered self-destruction and exposing oneself to danger?

A mother's refusal of her son's kidney donation is not considered self-killing (suicide) and does not incur sin. Donating organs and accepting them is not a religious obligation; rather, it is a matter of scholarly discussion among jurists regarding its permissibility, detestability, or desirability. Jurists have stipulated that whoever refrains from medical treatment and dies as a result does not sin, because healing is not guaranteed, unlike abstaining from food and drink until death. Furthermore, medical treatment involving organ transplantation differs from other forms due to the harm it poses to the donor and the great favor it entails.
