Sunan Abi Dawud Book 2, Hadith 111
He (the prophet) taught me IQAMAH (to pronounce each phrase) twice: 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: Allah is most great. Allah is great; there is no god but Allah.
Abu Dawud said: The narrator ‘Abd al-Razzaq said; You pronounce IQAMAH for announcing the prayer; you must say twice: the time for prayer has come, the time for prayer has come. (The Prophet said to Abu Mahdhurah): did you listen (to me)? Abu Mahdhurah would not have the hair of his forehead cut, nor would he separate them (from him) because the Prophet (ﷺ) wiped over them.
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. Lowering your voice while saying them (these words). Then you must raise your voice in making the testimony: I testify that there is no god but Allah, I testify there is no god but Allah; I testify Muhammad is the Messenger of Allah, I testify Muhammad is the Messenger of Allah. Come to prayer, come to prayer; come to salvation, come to salvation. If it is the morning prayer, you must pronounce; prayer is better than sleep, prayer is better than sleep, 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)
