Volume 2, Book 13, Number 37:
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 Muadh-dhin pronounced the Adhan saying, “Allahu-Akbar, Allahu Akbar”,
Muawiya said: “Allah Akbar, Allahu Akbar.” And when the Muadh-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 Muadh-dhin pronounced the Adhan I heard Allah’s Apostle on this very pulpit saying
what you have just heard me saying”.
