Sunan Abi Dawud Book 2, Hadith 113
The Messenger of Allah (May peace be upon him) himself taught me the call to prayer (adhan). He asked me to pronounce: 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 Messenger of Allah. Then repeat and raise your voice; 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; Allah is most great. Allah is most great; there is no god but Allah.
come to prayer, come to prayer, come to salvation; Allah is most great, Allah is most great: there is no god but Allah. IQAMAH runs: 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; come to prayer; come to prayer: come to salvation. Come to salvation; the time for prayer has come the time for prayer has come: Allah is most great, Allah is most great: there is no god but Allah. This is recorded in his collection (i.e., in the collection of the narrator Hammam b. Yahya) according to the tradition reported by Abu Mahdhurah (i.e., IQAMAH contains seventeen phrases)
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.
