question #1 Sahih Muslim 1190a, Book 15, Hadith 42 : What is the significance of using perfume during the state of Ihram in Islamic tradition?

I still seem to see the glistening of the perfume where the hair parted on Allah’s Messenger’s (ﷺ) head as he was in the state of Ihram, and Khalaf (one of the narrators) did not say: As he was in the state of Ihram, but said: That was the perfume of Ihram.
