ʿA’ishah said ; I used to perfume the Messenger of Allah (SWAS) preparatory to his entering the sacred state before he put on Ihram, and preparatory to putting off Ihram before he made the circuits round the House (the Ka’bah).  

كُنْتُ أُطَيِّبُ رَسُولَ اللَّهِ ﷺ لإِحْرَامِهِ قَبْلَ أَنْ يُحْرِمَ وَلإِحْلاَلِهِ قَبْلَ أَنْ يَطُوفَ بِالْبَيْتِ  

I still seem to see the glistening of the perfume where the hair was parted on the head of the Messenger of Allah (SWAS) while he was wearing Ihram.  

كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الْمِسْكِ فِي مَفْرِقِ رَسُولِ اللَّهِ ﷺ وَهُوَ مُحْرِمٌ
