Sahih Muslim Book - 5, Hadith - 1343

وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا أَبِى حَدَّثَنَا هِشَامٌ عَنْ أَبِى الزُّبَيْرِ قَالَ كَانَ ابْنُ الزُّبَيْرِ يَقُولُ فِى 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 -صلى الله عليه وسلم- يُهَلِّلُ بِهِنَّ دُبُرَ كُلِّ صَلاَةٍ.

Hisham narrated that Abu Az-Zubair said: "Ibn Az-Zubair used to say, following every prayer, after he had said the Taslim: 'La ilaha ill-Allahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu wa huwa 'ala kulli shay'in qadir. La hawla wa la quwwata illa billahi, la ilaha ill-Allahu, wa la na'budu illa iyyahu, lahun-ni'matu wa lahul-fadlu, wa lahuth-thana 'ul-hasan, la ilaha ill-Allahu, mukhlisina lahuddina wa law karihal-kafirun (There is none worthy of worship but Allah alone, with no partner or associate. His is the Dominion, to Him be praise, and He is Able to do all things. There is no power and no strength except with Allah. There is none worthy of worship but Allah and we worship none but Him. To Him belong all grace and favor, and to Him be glorious praise. There is none worthy of worship but Allah and we are sincere in faith and devotion to Him even though the disbelievers may detest it.)' He said: 'The Messenger of Allah (s.a.w) used to recite these words following every prayer."'
