question #2 Sahih al-Bukhari 3287, Book 59, Hadith 96 : What significance does being given Allah’s Refuge through the Prophet’s tongue hold for a companion?

I went to Sham (and asked. “Who is here?”), The people said, “Abu Ad-Darda.” Abu Darda said, “Is
the person whom Allah has protected against Satan, (as Allah’s Messenger (ﷺ) said) amongst you”. The subnarrator,
Mughira said that the person who was given Allah’s Refuge through the tongue of the
Prophet was `Ammar (bin Yasir).
