Purchasing a Qurbani Sheep Jointly

Q: If due to ignorance my friend and I purchased a sheep jointly; he gave half the price and I gave half. Now we realized that we cannot share this sheep for qurbani purposes. What do we do in this case?

A: One of you should give his half of the sheep to the other, so that the second person slaughters the whole sheep on behalf of himself. After doing so, he then makes an intention to convey the thawaab of his qurbani to you as well. In this way, both of you will achieve the objective of earning thawaab.
