Making intention for the person who purchased the qurbaani animal when slaughtering
Q: This year I gave my qurbaani money to the Muazzin and told him to give it to his family in Mozambique and purchase an animal for qurbaani. They purchased a goat.
My question is: In order for my qurbaani to be valid, is it necessary for the one slaughtering to make a niyyah to slaughter on my behalf?
