Standing for the teacher when he enters

Question:
Honorable Shaykh, may Allah grant you success, is it permissible to stand for a teacher when he enters?

Answer:
No, it is not permissible to stand for a person out of respect for him. Standing to greet him is fine, or to serve him if he needs service. When they needed to, they would dismount from the horse or the donkey because he was injured (may Allah be pleased with him). If the one arriving needs service, or if you are greeting him, there is no harm. But standing out of respect for him is not permissible. Yes.
