[Machine] Narrated by the Prophet Muhammad ﷺ , he said, "When the Mu'adhdhin calls for prayer, he should say what he says until he reaches the part where he says 'Hayya 'ala as-Salah' (Come to prayer). At this point, he should say, 'La hawla wa la quwwata illa billah' (There is no power or strength except with Allah)."  

عَنِ النَّبِيِّ ﷺ قَالَ كَانَ إِذَا سَمِعَ الْمُؤَذِّنَ قَالَ مِثْلَ مَا يَقُولُ حَتَّى إِذَا بَلَغَ حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الْفَلَاحِقَالَ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ  

[Machine] The Prophet ﷺ used to say when he heard the muadhin, he would say as he says. When he said "Hayya 'ala as-salah" he would say "La hawla wa la quwwata illa billah".  

كَانَ النَّبِيُّ ﷺ إِذَا سَمِعَ الْمُؤَذِّنَ قَالَ كَمَا يَقُولُ فَإِذَا قَالَ حَيَّ عَلَى الصَّلَاةِ حَيَّ عَلَى الْفَلَاحِ قَالَ «لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ»
