What Ibn az-Zubayr said after every prayer
He would say it out loud when the prayer ended.
لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ لاَ إِلَهَ إِلاَّ اللَّهُ لاَ نَعْبُدُ إِلاَّ إِيَّاهُ لَهُ النِّعْمَةُ
Lā ḥawla wa lā quwwata illā bi-Llāh. Lā ilāha illā-Llāh, lā naʿbudu illā iyyāh, lahu-n-niʿmah
“There is no power and no strength except with Allah. There is no god but Allah. We worship none but Him. To Him belongs every favour.”
Where this comes from
Abu az-Zubayr says Abdullah ibn az-Zubayr used to declare it at the end of every prayer, and that he had it from the Prophet, who said it after each one.
The full narration
Abu al-Zubair said:'Abd Allah b. al-Zubair used to recite this supplication after each (prescribed) prayer. He then narrated a similar supplication and added to it: "There is no might and no power except in Allah; there is no god but Allah Whom alone we worship. To Him belongs wealth." The narrator then transmitted the rest of tradition
