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.  

مسلم:٥٩٤b – 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 ﷺ يُهَلِّلُ بِهِنَّ دُبُرَ كُلِّ صَلاَةٍ

Ibn Zubair uttered at the end of every prayer after pronouncing salutation (these words):" There is no god but Allah. He is alone. There is no partner with Him. Sovereignty belongs to Him and He is Potent over everything. There is no might or power except with Allah. There is no god but Allah and we do not worship but Him alone. To Him belong all bounties, to Him belongs all Grace, and to Him is worthy praise accorded. There is no god but Allah, to Whom we are sincere in devotion, even though the unbelievers should disapprove it." (The narrator said): He (the Holy Prophet) uttered it at the end of every (obligatory) prayer.  

مسلم:٥٩٤a – وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا أَبِي حَدَّثَنَا هِشَامٌ عَنْ أَبِي الزُّبَيْرِ قَالَ كَانَ ابْنُ الزُّبَيْرِ يَقُولُ فِي دُبُرِ كُلِّ صَلاَةٍ حِينَ يُسَلِّمُ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ لاَ إِلَهَ إِلاَّ اللَّهُ وَلاَ نَعْبُدُ إِلاَّ إِيَّاهُ لَهُ النِّعْمَةُ وَلَهُ الْفَضْلُ وَلَهُ الثَّنَاءُ الْحَسَنُ لاَ إِلَهَ إِلاَّ اللَّهُ مُخْلِصِينَ لَهُ الدِّينَ وَلَوْ كَرِهَ الْكَافِرُونَ

وَقَالَ كَانَ رَسُولُ اللَّهِ ﷺ يُهَلِّلُ بِهِنَّ دُبُرَ كُلِّ صَلاَةٍ
