Show respect towards elders and those in positions of power or authority over you.

This hadith is about the action of wiping one's head, which was done by the Messenger of Allah, peace be upon him. It is narrated that Ali ibn Abi Talib saw the Messenger of Allah wiping his head once. This action has been taken as an example for Muslims to follow and it is a sign of humility and respect towards Allah. It also serves as a reminder to Muslims to be humble in their actions and words when dealing with others, especially those who are in authority or have more knowledge than them. Furthermore, this hadith teaches us that we should always strive to show respect towards our elders and those who are in positions of power or authority over us.
