question #1 Sahih al-Bukhari 4118, Book 64, Hadith 162 : What significance does the presence of angels hold in Islamic battles or expeditions?

As if I am just now looking at the dust rising in the street of Banu Ghanm (in Medina) because of the
marching of Gabriel’s regiment when Allah’s Messenger (ﷺ) set out to Banu Quraiza (to attack them).
