What cultural faux pas should I try to avoid making in Medina?

"In Medina, it is important to respect the local customs and traditions. Dress modestly, covering your arms and legs, and women should also cover their hair. Public displays of affection are frowned upon, so avoid hugging, kissing, or holding hands in public. Do not take photographs of people without their permission, especially women. It is also considered disrespectful to take pictures of government buildings, military installations, and palaces. Alcohol is strictly prohibited in Saudi Arabia, so do not attempt to bring any into the country or consume it while you are there. Similarly, pork is not consumed due to religious beliefs, so avoid asking for it. During the holy month of Ramadan, eating, drinking, or smoking in public during daylight hours is considered disrespectful as Muslims fast from dawn until dusk. Avoid discussing sensitive topics such as politics, religion, and women's rights. Criticizing the royal family, the government, or the country's laws is considered a serious offense. Remember that Friday is the Islamic holy day, so many businesses will be closed. Also, during prayer times, which occur five times a day, many shops and services will close temporarily. Always use your right hand for eating, shaking hands, and giving or receiving items, as the left hand is considered unclean. Women should not travel alone, and they should always be accompanied by a male guardian, known as a 'mahram', when in public. Lastly, non-Muslims are not allowed in certain parts of the city, including the Prophet's Mosque, so be respectful of these restrictions," remarked another expat who made the move to Medina, Saudi Arabia.
