Abdullah ibn Az-Zubayr (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) would say aloud after finishing his prayer:
"There is no god but Allah alone, with no partner. To Him belongs the dominion and to Him belongs all praise, and He is over all things competent. There is no power nor strength except with Allah. There is no god but Allah, and we worship none but Him. To Him belongs all favor, grace, and excellent praise. There is no god but Allah, sincere in faith to Him, even if the disbelievers dislike it." [Narrated by Muslim]
In Al-Umm, this is understood as a method of teaching. Once the teaching is accomplished, it is stopped. As mentioned in Al-Mirqah. In Al-Madkhal, it is said: "People should be cautious of raising their voices in remembrance and supplication after finishing the prayer in congregation, as this is an innovation."
Arabic quotation in the English source
لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ، لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ، لَا إِلَهَ إِلَّا اللَّهُ، وَلَا نَعْبُدُ إِلَّا إِيَّاهُ، لَهُ النَّعْمَةُ، وَلَهُ الْفَضْلُ، وَلَهُ الثَّنَاءُ الْحَسَنُ ، لَا إِلَهَ إِلَّا اللهُ مُخْلِصِينَ لَهُ الدِّيْنُ، وَلَوْ كَرِهَ الْكَافِرُوْنَ
