People standing up for someone who enters upon them

Question:
The questioner says: We see many people standing up for a person when he enters to greet him. Does this fall under the prohibition, or is it according to the custom of the people of the country?

Answer:
No, if they stand up to greet him and receive him, that is a good thing. But if they stand up out of respect for him, not out of kindness to him, such as students standing up for a teacher, that is not permissible. This is prohibited. Yes. Or if he sits and they stand up over him, that is not permissible except for guarding. If he is a person in authority and there is danger to him, and they are guarding him, they stand at his head for the purpose of guarding; there is no harm in that. This is for a need and necessity. But if they stand up over him out of exalting him, that is not permissible. This is the action of the Persians; the Persians did this with their kings. Yes.
