The Book of Pilgrimage
15/7. Chapter:
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
Sahih Muslim
وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، وَسَعِيدُ بْنُ مَنْصُورٍ، وَأَبُو الرَّبِيعِ، وَخَلَفُ بْنُ هِشَامٍ، وَقُتَيْبَةُ، بْنُ سَعِيدٍ قَالَ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرُونَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفْرِقِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ مُحْرِمٌ . وَلَمْ يَقُلْ خَلَفٌ وَهُوَ مُحْرِمٌ . وَلَكِنَّهُ قَالَ وَذَاكَ طِيبُ إِحْرَامِهِ .
'A'isha (Allah be pleased with her) reported: I still seem to see the glistening of the perfume where the hair parted on Allah's Messenger's (ﷺ) head as he was in the state of Ihram, and Khalaf (one of the narrators) did not say: As he was in the state of Ihram, but said: That was the perfume of Ihram.
