(the wife of the Prophet (p.b.u.h) I used to scent Allah's Messenger (ﷺ) when he wanted to assume Ihram and also on finishing Ihram before the Tawaf round the Ka`ba (Tawaf-al-ifada).

← Previous Hadith Ibn `Umar used to oil his hair. I told that to Ibrahim who said, "What do you think about this statement: Narrated Aswad from `Aisha: As if I were now observing the glitter of the scent in the parting of the hair of the Prophet (ﷺ) while he was Muhrim?"

Sahih al-Bukhari Book 25, Hadith 25 Next Hadith → I heard that Allah's Messenger (ﷺ) assumed Ihram with his hair matted together.
