وَحَدَّثَنَاهُ أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِي الزُّبَيْرِ، مَوْلًى لَهُمْ أَنَّ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ، كَانَ يُهَلِّلُ دُبُرَ كُلِّ صَلاَةٍ . بِمِثْلِ حَدِيثِ ابْنِ نُمَيْرٍ وَقَالَ فِي آخِرِهِ ثُمَّ يَقُولُ ابْنُ الزُّبَيْرِ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُهَلِّلُ بِهِنَّ دُبُرَ كُلِّ صَلاَةٍ .
Abdullah b Zubair used to say La ilaha il-Allah at the end of every prayer like the hadith narrated by Ibn Numair and he reported it in the end, and then reported Ibn Zubair saying: The Messenger of Allah (ﷺ) uttered La ilaha il-Allah at the end of every prayer.
