Can you explain the meaning of this hadith and is it authentic?
Narrated Mu’awiyah (rad): Allah’s Messenger (saW) said: “The eye (when awake) is the string of the anus (to stop air escaping), and if the two eyes sleep the string is untied”. [Reported by Ahmad and At-Tabarani who added, “Whoever sleeps should perform ablution]”
