I still seem to see the glistening of the perfume where the hair parted on Messenger of Allah'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.
كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفْرِقِ رَسُولِ اللَّهِ ﷺ وَهُوَ مُحْرِمٌ وَلَمْ يَقُلْ خَلَفٌ وَهُوَ مُحْرِمٌ وَلَكِنَّهُ قَالَ وَذَاكَ طِيبُ إِحْرَامِهِ
