Slaughtering animals at shrines

A: Slaughtering (sacrificing) at shrines is considered major Shirk (associating others with Allah in His Divinity or worship). A person who does this is cursed, as is authentically established that `Aly, (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) said: Allah has cursed the one who slaughters (a sacrifice) to other than Allah.
