Islamic State has sanctioned the harvesting of human organs in a previously undisclosed ruling by the group’s Islamic scholars, raising concerns that the violent extremist group may be trafficking in body parts.

The ruling, contained in a January 31, 2015 document reviewed by Reuters, says taking organs from a living captive to save a Muslim’s life, even if it is fatal for the captive, is permissible.

Reuters couldn’t independently confirm the authenticity of the document. U.S. officials say it was among a trove of data and other information obtained by U.S. special forces in a raid in eastern Syria in May.

“The apostate’s life and organs don’t have to be respected and may be taken with impunity,” says the document, which is in the form of a fatwa, or religious ruling, from the Islamic State’s Research and Fatwa Committee.

“Organs that end the captive’s life if removed: The removal of that type is also not prohibited,” Fatwa Number 68 says, according to a U.S. government translation.
