What is the ruling on standing up for someone who enters a gathering while they are sitting?

The questioner : What is the ruling on standing up for the person who enters? Whether the person entering wants people to stand for him or not, some people consider it a slight against them if they do not stand for them, because it is a custom with them, not arrogance on their part?

The Shaykh : Standing up for the person who enters is contrary to the practice of the Companions with the Messenger of Allah (peace and blessings be upon him and his family), for the Companions did not stand up when the Prophet (peace and blessings be upon him and his family) entered, because they knew that he disliked it. However, if people become accustomed to standing up, and there is harm in not standing, or it causes the hearts of those in the gathering to hold a grudge against the person entering, then there is no harm in a person standing up. Thaqif came to the Messenger of Allah (peace and blessings be upon him and his family) and he stood up for them. The scholars (may Allah have mercy on them) said: "There is standing up to a person, standing up for a person, and standing up over a person", which differs according to the preposition. The first is standing up to whom? To him. The second is standing up for him. The third is standing up over him. As for standing up to him, it is a recommended practice (sunnah) if the person you are standing up to is worthy of it, such as if a man enters and you stand up to greet him, shake his hand, and greet him. This is a recommended practice (sunnah) for one who is worthy. The evidence for this is the story of Sa'd ibn Mu'adh (may Allah be pleased with him)
As for standing up for him, it is what you heard: that it is better for people not to make it a habit, and that a person should sit wherever the gathering ends for him. But if people have made it a habit, and there is some harm in not doing it, or it causes the hearts to hold a grudge against the person entering, then let him stand up, and there is no harm.
The third is: standing up over him. This is prohibited. The Prophet (peace and blessings be upon him and his family) prohibited it, to the extent that when he prayed one day while sitting, and the people behind him were praying while standing, he gestured to them to sit and said: meaning standing up over a person. Except if there is a benefit for the Muslims and annoyance for the disbelievers in it, then there is no harm in it, as happened with al-Mughirah ibn Shu'bah in the Battle of al-Hudaybiyyah when he was standing over the head of the Prophet (peace and blessings be upon him and his family) with a sword, and the Prophet (peace and blessings be upon him and his family) was negotiating with the envoys of the disbelievers. This is undoubtedly good, because it honors the Muslims and humiliates the disbelievers. Similarly, if one stands over a man to protect him from fear, then there is no harm in this, as it serves as a guard. But if one stands over his head to honor him, then this is not permissible. Yes.
