Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، وَيَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، عَنْ إِبْرَاهِيمَ بْنِ مُحَمَّدِ بْنِ الْمُنْتَشِرِ، عَنْ أَبِيهِ، قَالَ ذَكَرْتُهُ لِعَائِشَةَ فَقَالَتْ يَرْحَمُ اللَّهُ أَبَا عَبْدِ الرَّحْمَنِ، كُنْتُ أُطَيِّبُ رَسُولَ اللَّهِ صلى الله عليه وسلم،فَيَطُوفُ عَلَى نِسَائِهِ، ثُمَّ يُصْبِحُ مُحْرِمًا يَنْضَخُ طِيبًا.
Translation
Narrated Muhammad bin Al-Muntathir
on the authority of his father that he had asked `Aisha (about the Hadith of Ibn `Umar). She said, "May Allah be Merciful to Abu `Abdur-Rahman. I used to put scent on Allah's Messenger (ﷺ) and he used to go round his wives, and in the morning he assumed the Ihram, and the fragrance of scent was still coming out from his body."
