Chapter: The shade of angels on the martyr
Narrated Jabir:
My father's mutilated body was brought to the Prophet (ﷺ) and was placed in front of him. I went to uncover his face but my companions forbade me. Then mourning cries of a lady were heard, and it was said that she was either the daughter or the sister of `Amr. The Prophet (ﷺ) said, "Why is she crying?" Or said, "Do not cry, for the angels are still shading him with their wings." (Al-Bukhari asked Sadqa, a sub-narrator, "Does the narration include the expression: 'Till he was lifted?' " The latter replied, "Jabir may have said it.")
