وَحَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ، حَدَّثَنَا ابْنُ عُلَيَّةَ، حَدَّثَنَا الْحَجَّاجُ بْنُ أَبِي عُثْمَانَ، حَدَّثَنِي أَبُو الزُّبَيْرِ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ، يَخْطُبُ عَلَى هَذَا الْمِنْبَرِ وَهُوَ يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقُولُ إِذَا سَلَّمَ فِي دُبُرِ الصَّلاَةِ أَوِ الصَّلَوَاتِ . فَذَكَرَ بِمِثْلِ حَدِيثِ هِشَامِ بْنِ عُرْوَةَ .
Abu Zubair reported: I heard Abdullah b. Zubair addressing (people) on the pulpit and saying: When the Messenger of Allah (ﷺ) pronounced salutation at the end of the prayer or prayers, and then he made a mention of the hadith as transmitted by Hisham b. 'Urwa.
