Ibn ʿUmar used to oil his hair. I told that to Ibrahim who said, "What do you think about this statement: Narrated Aswad from ʿAisha: 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?"
كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفَارِقِ رَسُولِ اللَّهِ ﷺ وَهُوَ مُحْرِمٌ
