Is it permissible to stand up for someone who enters in order to shake hands?

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: Is it permissible to stand up for someone who enters and greets the people? Is it permissible for us to stand up for him in order to shake his hand?

Answer:
Yes, because if you do not stand up, it will cause him some discomfort. Stand up for the salam; you do not stand up except for the sake of the honor of the greeting. It is not permissible to stand up out of respect for the person entering; rather, one stands up for the sake of the salam upon him. There is nothing wrong with it. Yes.
