سنن أبي داود

Abu Mahdhurah said that the apostle of Allah (May peace be upon him) taught him the call to prayer (adhan), saying: Allah is most great, Allah is most great; I testify that there is no god but Allah. He then narrated adhan like the one contained in the tradition transmitted by Ibn Juraij from ‘Abd al-aziz b. ‘abd al-Malik to the same effect. The version Malik b. Dinar has. I asked the son of Abu Mahdhurah, saying: Narrate to me the adhan of your father narrated from the Messenger of Allah (May peace be upon him). He said: Allah is most great, Allah is most great, that is all. Similar is the version narrated by Ja’far b. Sulaiman from the son of Abd Muhdhurah from his uncle on the authority of his grandfather, excepting that he said; Then repeat and raise your voice. Allah is most great. Allah is most great.
