The Ruling on the Order of Changing Evil and the Meaning of "Hand"

Question:
Honorable Shaykh, the hadith of the Prophet (peace and blessings be upon him) . Is it obligatory to follow the order of these levels, or does one look at the public benefit? And what is meant by "hand" here?

Answer:
This is an ordering, for the Messenger arranged them. He said: "Whoever among you sees an evil, let him change it with his hand; if he cannot, then with his tongue; and if he cannot, then with his heart, and that is the weakest of faith." So the one who is able to forbid evil with his hand must do so and not be content with his tongue. This includes the one in authority, the official who has jurisdiction, such as the members of the Committee for Promoting Virtue and Preventing Vice who have jurisdiction, and the head of the household who has jurisdiction over his family. He changes it with his hand. If he does not have jurisdiction, he moves to the tongue. He forbids it with his tongue, clarifies it, calls to Allah, and explains to them that this is not permissible, making this clear to them. This is forbidding with the tongue. As for the hand, he does not have the ability. If he does not have the ability to clarify with his tongue, or if he cannot speak in the darkness, or if he is only able to speak in a way that he knows he can speak, then he moves to forbidding with the heart. He forbids the evil with his heart.
