Sahih Bukhari 914

حَدَّثَنَا بْنُ مُقَاتِلٍ ، قَالَ : أَخْبَرَنَا عَبْدُ اللَّهِ ، قَالَ : أَخْبَرَنَا أَبُو بَكْرِ بْنُ عُثْمَانَ بْنِ سَهْلِ بْنِ حُنَيْفٍ ، عَنْ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ ، قَالَ : سَمِعْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ وَهُوَ جَالِسٌ عَلَى الْمِنْبَرِ أَذَّنَ الْمُؤَذِّنُ ، قَالَ : اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ، قَالَ مُعَاوِيَةُ : اللَّهُ أَكْبَرُ اللَّهُ أَكْبَرُ ، قَالَ : أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ ، فَقَالَ مُعَاوِيَةُ : وَأَنَا ، فَقَالَ : أَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ، فَقَالَ مُعَاوِيَةُ : وَأَنَا ، فَلَمَّا أَنْ قَضَى التَّأْذِينَ ، قَالَ : يَا أَيُّهَا النَّاسُ ، إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى هَذَا الْمَجْلِسِ حِينَ أَذَّنَ الْمُؤَذِّنُ يَقُولُ مَا سَمِعْتُمْ مِنِّي مِنْ مَقَالَتِي .

Narrated Abu Umama bin Sahl bin Hunaif: I heard Muawiya bin Abi Sufyan (repeating the statements of the Adhan) while he was sitting on the pulpit. When the Mu'adh-dhin pronounced the Adhan saying, Allahu-Akbar, Allahu Akbar , Muawiya said: Allah Akbar, Allahu Akbar. And when the Mu'adh-dhin said, Ash-hadu an la ilaha illal-lah (I testify that none has the right to be worshipped but Allah) , Muawiya said, And (so do) I . When he said, Ash-hadu anna Muhammadan Rasulullah (I testify that Muhammad is Allah's Apostle), Muawiya said, And (so do) I . When the Adhan was finished, Muawiya said, O people, when the Mu'adh-dhin pronounced the Adhan I heard Allah's Apostle on this very pulpit saying what you have just heard me saying .
