A’ishah (RAA) narrated, ‘I used to apply perfume to the Prophet (ﷺ) when he intended to enter the state of Ihram, before he put on his Ihram (garments). And again when he ended his state of Ihram, but before he had made Tawaf around the Ka’bah.' Agreed upon.

وَعَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا قَالَتْ: { كُنْتُ أُطَيِّبُ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-لِإِحْرَامِهِ قَبْلَ أَنْ يُحْرِمَ, وَلِحِلِّهِ قَبْلَ أَنْ يَطُوفَ بِالْبَيْتِ } مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
