Ibn Zubayr used to say after every prayer, immediately upon giving the salam, "There is no god but Allah alone, with no partner. To Him belongs the dominion, to Him belongs all praise, and He has power over all things. There is no might nor power except through Allah. There is no god but Allah, and we worship none but Him. To Him belongs every blessing, to Him belongs all bounty, and to Him belongs the most beautiful praise. There is no god but Allah, devoting our worship sincerely to Him, even if the disbelievers detest it."He said, "The Messenger of Allah ﷺ used to declare these words after every prayer."
كان ابن الزبير يقول في دبر كل صلاة حين يسلم: لا إله إلا الله وحده لا شريك له، له الملك، وله الحمد، وهو على كل شيء قدير، لا حول ولا قوة إلا بالله، لا إله إلا الله، ولا نعبد إلا إياه، له النعمة، وله الفضل، وله الثناء الحسن، لا إله إلا الله مخلصين له الدين، ولو كره الكافرون. وقال: كان رسول الله ﷺ يهلل بهن دبر كل صلاة.
Muslim narrated it in "Mosques and Places of Prayer" (594) from Muhammad bin Abdullah bin Numayr, who said, my father narrated to us, Hisham narrated to us, from Abu Zubayr (who is Muhammad bin Muslim al-Makki), who said, and he mentioned it.
