Musnad Ahmad 284:7

'Abdullah ibn Numayr narrated to us, he said: Hisham—meaning Ibn 'Urwah ibn al-Zubayr—narrated to us, from Abu al-Zubayr, he said: 'Abdullah ibn al-Zubayr used to say at the end of every prayer when he would perform the taslim: "There is no god but Allah, alone, having no partner. To Him belongs the dominion, and to Him belongs the praise, and He is capable of all things. There is no power and no strength except by Allah. There is no god but Allah, and we worship none but Him. To Him belongs the blessing, and to Him belongs the bounty, and to Him belongs the good commendation. There is no god but Allah, [we are] sincere to Him in religion, even if the disbelievers hate it." He said: "And the Messenger of Allah (may Allah bless him and grant him peace) used to proclaim these [words] at the end of every prayer."
