question #1 Sahih Muslim 342, Book 3, Hadith 96 : What is the significance of maintaining confidentiality when someone shares a secret with you?

The Messenger of Allah (ﷺ) one day made me mount behind him and he confided to me something secret which I would not disclose to anybody; and the Messenger of Allah (ﷺ) liked the concealment provided by a lofty place or cluster of dates (while answering the call of nature), Ibn Asma’ said in his narration: It implied an enclosure of the date-trees.
