The ruling on one who is obligated to offer seven sheep but slaughters a camel or a cow

Question : If seven sheep become obligatory upon him, does a cow or a camel suffice for him?

Answer : The answer is yes. It has been said that it does not suffice, but it should be said that it suffices, provided that this is not in the case of the expiation for hunting. In the expiation for hunting, similarity is required.
