It is Permissible to put on perfume when Entering Ihram
أَخْبَرَنَا سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ أَبُو عُبَيْدِ اللَّهِ الْمَخْزُومِيُّ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ طَيَّبْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم لِحُرْمِهِ حِينَ أَحْرَمَ وَلِحِلِّهِ بَعْدَ مَا رَمَى جَمْرَةَ الْعَقَبَةِ 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.''
