What to say on hearing the Adhan
Sahih Bukhari
حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ، قَالَ حَدَّثَنَا هِشَامٌ، عَنْ يَحْيَى، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ بْنِ الْحَارِثِ، قَالَ حَدَّثَنِي عِيسَى بْنُ طَلْحَةَ، أَنَّهُ سَمِعَ مُعَاوِيَةَ، يَوْمًا فَقَالَ مِثْلَهُ إِلَى قَوْلِهِ " وَأَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ ".
Narrated `Isa bin Talha: that he had heard Muawiya repeating the words of Adhan up to "Wa ash-hadu anna Muhammadan rasulul-lah (and I testify that Muhammad is Allah's Messenger (ﷺ).)"
