أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، قَالَ حَدَّثَنَا بِشْرٌ، - يَعْنِي ابْنَ الْمُفَضَّلِ - قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفْرِقِ رَأْسِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ مُحْرِمٌ ‏.‏
