Ruling on shaving the hair between the earlobes and the jaw

Question:
He also asks and says: Is it permissible to shave the hair connecting the earlobes and the jaw, while keeping the beard? And is this hair considered part of the beard?

Answer:
Whatever grows on the cheeks is part of the beard, and whatever is above the cheeks, above the bone, is part of the head. What is above the bone that aligns with the ear is part of the head, and what is below it, on the cheek, is part of the beard. The author of al-Qamus says: "The beard: the hair growing on the cheeks and the chin." So one leaves the hair on the cheeks and the chin, because that is the beard. Yes.
