question #3 Sahih al-Bukhari 1279, Book 23, Hadith 40 : How does the use of perfume relate to the end of the mourning period in Islamic tradition?

One of the sons of Um ‘Atiyya died, and when it was the third day she asked for a yellow perfume and
put it over her body, and said, “We were forbidden to mourn for more than three days except for our
husbands.”
