Question
A person swore to drink the blood of the dog that ate one of his rabbits, and indeed he killed it and drank two drops of its blood, then drank water afterward. What is the ruling on his action? What should he do?
Answer
: I say, and with God's success: This is a sin; because the dog's blood is impure, and it is not permissible to drink it, and one must seek forgiveness, and God knows best.
