باب اسْتِحْبَابِ الذِّكْرِ بَعْدَ الصَّلاَةِ وَبَيَان صِفَتِهِ ‏
Sahih Muslim 594 e

Abu Zubair al-Makki reported that he had heard 'Abdullah b. Zubair uttering (the words) like that of the hadith (narrated above) at the end of the prayer after pronouncing salutation. He at the conclusion also said that he was making a mention of that from the Messenger of Allah (ﷺ).

وَحَدَّثَنِي مُحَمَّدُ بْنُ سَلَمَةَ الْمُرَادِيُّ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، عَنْ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ سَالِمٍ، عَنْ مُوسَى بْنِ عُقْبَةَ، أَنَّ أَبَا الزُّبَيْرِ الْمَكِّيَّ، حَدَّثَهُ أَنَّهُ، سَمِعَ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ، وَهُوَ يَقُولُ فِي إِثْرِ الصَّلاَةِ إِذَا سَلَّمَ ‏.‏ بِمِثْلِ حَدِيثِهِمَا وَقَالَ فِي آخِرِهِ وَكَانَ يَذْكُرُ ذَلِكَ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
