The Excellence of the Adhan and the Response to the Mu’adhdhin - Section 3
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا سَمِعَ الْمُؤَذِّنَ يَتَشَهَّدُ قَالَ: «وَأَنَا وَأَنَا» . رَوَاهُ أَبُو دَاوُد
‘A’isha said that when the Prophet (ﷺ) heard the mu’adhdhin uttering the testimony, he said, “I too, I too.” Abu Dawud transmitted it.
