Sahih Muslim 1189
Sahih Muslim · Book 15: The Book of Pilgrimage · It is recommended to apply perfume just before entering Ihram, and it is recommended to use Musk, and it does not matter if its glistening traces remain
'A'isha (Allah be pleased with her) reported:
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ ، حَدَّثَنَا ابْنُ أَبِي فُدَيْكٍ ، أَخْبَرَنَا الضَّحَّاكُ ، عَنْ أَبِي الرِّجَالِ ، عَنْ أُمِّهِ ، عَنْ عَائِشَةَ ، - رضى الله عنها - أَنَّهَا قَالَتْ طَيَّبْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم لِحُرْمِهِ حِينَ أَحْرَمَ وَلِحِلِّهِ قَبْلَ أَنْ يُفِيضَ بِأَطْيَبِ مَا وَجَدْتُ .
I applied the best available perfume I could find to the Messenger of Allah (ﷺ) before he entered upon the state of Ihram and after he was free from it.
