It is reported that the Prophet (peace and blessings be upon him) “forbade a man from placing one of his legs over the other while lying on his back”? How is that?

The questioner : The wording of the hadith is: “He forbade a man from placing one of his legs over the other while lying on his back”?

The Shaykh : Approximately as I am now, and this is a matter of precaution; because their custom was not to wear trousers under the shirt, so a person would be exposed to the risk of uncovering his private parts; otherwise, it is established from the Prophet (peace and blessings be upon him) that he lay on his back and placed one of his legs over the other.
Yes.
