Sunan an-Nasa'i, Volume 1, Book 7, Hadith 678 (DarusSalam) ⓘ

It was narrated that 'Alqamah bin Waqqas said: "I was with Mu'awiyah when the Mu'adhdhin called the Adhan. Muawiyah said what the Mu'adhdhin said, but when he said: 'Hayya 'alas-salah (come to prayer),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah);' and when he said: 'Hayya 'alal-falah (come to prosperity),' he said: 'La hawla wa la quwwata illa Billah (There is no power and no strength except with Allah).' After that he said what the Mu'adhdhin said, then he said: 'I heard the Messenger of Allah saying exactly like that.'"

أَخْبَرَنَا مُجَاهِدُ بْنُ مُوسَى، وَإِبْرَاهِيمُ بْنُ الْحَسَنِ الْمِقْسَمِيُّ، قَالاَ حَدَّثَنَا حَجَّاجٌ، قَالَ ابْنُ جُرَيْجٍ أَخْبَرَنِي عَمْرُو بْنُ يَحْيَى، أَنَّ عِيسَى بْنَ عُمَرَ، أَخْبَرَهُ عَنْ عَبْدِ اللَّهِ بْنِ عَلْقَمَةَ بْنِ وَقَّاصٍ، عَنْ عَلْقَمَةَ بْنِ وَقَّاصٍ، قَالَ إِنِّي عِنْدَ مُعَاوِيَةَ إِذْ أَذَّنَ مُؤَذِّنُهُ فَقَالَ مُعَاوِيَةُ كَمَا قَالَ الْمُؤَذِّنُ حَتَّى إِذَا قَالَ حَىَّ عَلَى الصَّلاَةِ قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ فَلَمَّا قَالَ حَىَّ عَلَى الْفَلاَحِ قَالَ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ وَقَالَ بَعْدَ ذَلِكَ مَا قَالَ الْمُؤَذِّنُ ثُمَّ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ مِثْلَ ذَلِكَ ‏.‏
