Using the story of 'Umar and Hamzah and the story of the neighbor's complaint as evidence for demonstrations

Question:
The question states: Some people who have frequently argued for the permissibility of demonstrations here cite the story of the Islam of 'Umar ibn al-Khattab and Hamzah, their exiting the safety of the two rows to pray in the Sacred House, just as these people cite the story of the man who came to buy a rental from the Messenger of Allah (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said to him, "Take your goods out in front of your house," and so on.

Answer:
My brother, in the story of 'Umar and Hamzah (may Allah be pleased with them both), when they embraced Islam, they went out to the Sacred Mosque. This was a demonstration in the eyes of whom? In the eyes of the disbelievers. It was not a demonstration in the eyes of the Muslims. This was a demonstration in the eyes of the disbelievers, not in the eyes of the Muslims. A demonstration among Muslims is not permissible.
Second, this narration has a defect and is not established. But even if we assume it is established, they did not demonstrate. They went out to pray; they wanted to pray in the Sacred Mosque. They did not demonstrate, shout, or make a commotion; they did not do that. They only went out to pray. Does anyone prevent going out to the Sacred Mosque? They went out together and prayed in the Sacred Mosque. Is this evidence for demonstrations? As for the man taking his goods out so that people would know that his neighbor was harming him, that is not a demonstration. It was to let people know that his neighbor was harming him; it was a sign of the neighbor's harm, not a demonstration. A demonstration with vessels and goods is a demonstration. Yes.
