Mutah is prohibited

Book: “Wasael ush shia”, chapter Nikah.
Author: Hurr al Amele.

Ali ibn Abe Taleeb (radi Allahu anhu) said:

“Prohet (sallalahu alayhi wa ala alihi wa salam) forbade meat of domestic donkey and mutah marriage in the day of khaybar”.

Author of book tried to explain it like taqiyah, that shows us that he accepted that narration as authentic.
