Arabic hadith text
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، وَأَبُو سَعِيدٍ الأَشَجُّ قَالُوا حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي الضُّحَى، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْكَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفَارِقِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ يُلَبِّي.
Translation
'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, while he was pronouncing Talbiya.
