(28) باب كَيْفَ الأَذَانُ
Abu Mahdhurah reported:
The Messenger of Allah (May peace be upon him) taught me the call to prayer (adhan) verbatim; Allah is most great, Allah is most great, Allah is most great, Allah is most great; I testify that there is no god but Allah, I testify that there is no god but Allah; I testify that Muhammad is the Messenger of Allah; I testify that Muhammad is the Messenger of Allah; I testify that there is no god but Allah. I testify that there is no god but Allah; I testify that Muhammad is the Messenger of Allah, I testify that Muhammad is the Messenger of Allah; come to prayer, come to prayer; come to salvation, come to salvation. He used to pronounce "prayer is better than sleep" in the dawn prayer.
