It is Permissible to put on perfume when Entering Ihram
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ طَيَّبْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم لإِحْرَامِهِ قَبْلَ أَنْ يُحْرِمَ وَلِحِلِّهِ قَبْلَ أَنْ يَطُوفَ بِالْبَيْتِ .
It was narrated that Aishah said: "I put perfume on the Messenger of Allah (ﷺ) for his Ihram when he entered Ihram, and for his exiting Ihram when he had stoned Jamrat Al-Aqabah, before he circumambulated the House.''
