Chapter 16: The Book of Pilgrimage
' A' isha (Allah be pleased with her) reported: 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.
