Does a person offer the salam when passing by a cemetery that has a wall?

Question : He says: Some of the brothers have reported from you that a person passing by a cemetery does not offer the salam while on his way, but rather he stops and enters the cemetery to offer the salam. What is the validity of this?

Answer : This is correct if it has a wall. As for if it is open, the scholars (may Allah have mercy on them) mentioned that if he passes by it, he offers the salam to the deceased.
