For any person, at the behest of another person, to slaughter a goat etc. for anyone other than Allah, such as for some Peer (saint) or deity, whether it is done by taking a wage or without a wage, is Shari'ah-wise impermissible and Haram. Furthermore, eating this slaughtered animal is also Haram, and such a person's Adhan, Iqamah, and Imamat are Makrooh Tahrimi (severely disliked). Yes, if they repent with a sincere heart, the dislike will be removed. (Aham Masail / Vol: 3 / Page: 39)
