Must a woman observe hijab and cover her awrah from jinn, even though we do not see them and they are everywhere?

The jinn are a creation of Allah whom we do not see. Therefore, Allah did not command us to conceal our awrah (private parts) from them, due to the difficulty involved in that. However, the Sharia contains what indicates high etiquette. So, whoever enters the lavatory says: "Bismillah (In the name of Allah)," so that this may be a screen between the eyes of the jinn and the awrah of the children of Adam. Scholars have determined that nudity is disliked (makrooh) because it contradicts modesty before Allah, based on the saying of the Prophet, peace and blessings be upon him: "Allah is more deserving that one should feel shy before Him than before people."
