Muawiyah ibn Haydah RA came from Yemen as one of the delegates to the Prophet ﷺ, and he saw him only this once in his life. He asked the Prophet ﷺ which parts of the awrah, the parts of the body that must be kept covered, may be shown and which may not. The Prophet ﷺ told him to cover his awrah from everyone but his spouse. Muawiyah RA then asked what to do when he was alone. The Prophet ﷺ replied that Allah has more right that one be shy of Him. This is the only hadith that speaks explicitly about the awrah.

O Messenger of Allah ﷺ, what is allowed to show of our awrah, and what is not allowed to show?
Cover your awrah from everyone other than your spouse.
What if I am alone?
There is more right upon Allah that you be shy of Him.
