(Imām Bukhārī narrates): Musaddad narrated the hadeeth to us, he said: Bishr bin Al-Mufaddal narrated the hadeeth to us, he said: Ubaidullah bin Umar narrated the hadeeth to us, from Nafi', from Hazrat Abdullah bin Umar, Allāh be pleased with them both, he said that
the Prophet ﷺ used to deliver two sermons (on the day of Jumu'ah), between which he used to sit.
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا بِشْرُ بْنُ المُفَضَّلِ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا، قَالَ
كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَخْطبُ خُطْبَتَيْنِ يَقْعُدُ بَيْنَهُمَا
