In general there has been broad support for organ donation
among most faith communities.  We understand that there may be differences of opinion even within any particular religious group.  Each decision to become a donor is a personal one.  We suggest that individuals consult with their faith leader if they have questions about their faith’s view of donation. 

The Fourth Conference of the Islamic Fiqh Council determined that transplantation offers “clear positive results” if practiced “...to achieve the aims of sharee'ah which tries to achieve all that is good and in the best interests of individuals and societies and promotes cooperation, compassion and selflessness.” Provided that “shar'i guidelines and controls that protect human dignity” are met, “It is permissible to transplant an organ from a dead person to a living person whose life or basic essential functions depend on that organ, subject to the condition that permission be given by the deceased before his death, or by his heirs after his death….” Regarding living donation, it is permissible to transplant organs such as a kidney and or a lung “in order to keep the beneficiary alive or to keep some essential or basic function of his body working.”
