Sunan an-Nasai
أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، قَالَ قَالَ لِي إِبْرَاهِيمُ حَدَّثَنِي الأَسْوَدُ، عَنْ عَائِشَةَ، رضى الله عنها قَالَتْ لَقَدْ كَانَ يُرَى وَبِيصُ الطِّيبِ فِي مَفَارِقِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ مُحْرِمٌ .
It was narrated that 'Aishah said: "The glistening of the perfume could be seen in the parting (of the hair) of the Messenger of Allah while he was in Ihram.''
