The ruling on a designated sacrificial animal if it is afflicted with a defect

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the ruling if a man designates a sacrificial animal and then its horn breaks, or its leg breaks, or it becomes ill, whether due to negligence or without negligence? What is the ruling in this case?

Answer:
As mentioned previously, if it was obligatory in his debt before designation by a vow or a bequest, then he is required to replace it if it becomes defective. However, if it was not obligatory in his debt before designation, but was merely voluntary and then he designated it, then if it becomes defective, he slaughters it and it is sufficient.
