Are there any hadiths concerning the impermissibility of a man being alone with a woman?

A man being alone with a woman who is not his mahram (definition) is forbidden. There are explicit and authentic prophetic hadiths that prohibit this, including: "No man is alone with a woman except with a mahram," and "Beware of entering upon women," and "Indeed, no man is alone with a woman but the third of them is Satan." Also, "Whoever believes in Allah and the Last Day should not be alone with a woman who is not his mahram," and "No man is ever alone with a woman except that Satan enters between them," and "For one of you to be stabbed in the head with an iron needle is better for him than to touch a woman who is not lawful for him."
