Muslim :: Book 4 : Hadith 740 - The Book of Prayers (Kitab Al-Salat)

Adhan


Abu Mahdhura said that the Apostle of Allah (may peace be upon him) taught him Adhan like this: 


Allah is the Greatest, Allah is the Greatest;
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, 
and it should be again repeated: 


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 the prayer (twice). Come to the prayer (twice).


Ishaq added: 
Allah is the Greatest, Allah is the Greatest; there Is no god but Allah.
