question #1 Sahih al-Bukhari 1293, Book 23, Hadith 51 : What is the significance of angels shading a martyr with their wings in Islamic belief?

On the day of the Battle of Uhud, my father was brought and he had been mutilated (in battle) and was placed
in front of Allah’s Messenger (ﷺ) and a sheet was over him. I went intending to uncover my father but my
people forbade me; again I wanted to uncover him but my people forbade me. Allah’s Messenger (ﷺ) gave
his order and he was shifted away. At that time he heard the voice of a crying woman and asked,
“Who is this?” They said, “It is the daughter or the sister of `Amr.” He said, “Why does she weep? (or
let her stop weeping), for the angels had been shading him with their wings till he (i.e. the body of the
martyr) was shifted away.”
