Al-Dāraquṭnī also preserves from Abū Maḥdhūrah a third chain of transmission, narrated by al-Ḥārith b. ʿUbayd from Muḥammad b. ʿAbd al-Malik, from Abū Maḥdhūrah, from his father, from his grandfather, who said:
“I said, ‘Messenger of Allah, teach me the sunnah of the adhān.’ He stroked the front of my head and said:
‘You say: Allah is most great, Allah is most great, Allah is most great, Allah is most great—raise your voice with these words. Then say: I bear witness that there is no god but Allah, I bear witness that there is no god but Allah; I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah—lower your voice with these words. Next, raise your voice again for the testimony and say: I bear witness that there is no god but Allah, I bear witness that there is no god but Allah; I bear witness that Muhammad is the Messenger of Allah, I bear witness that Muhammad is the Messenger of Allah. Come to prayer, come to prayer; come to success, come to success. Allah is most great, Allah is most great; there is no god but Allah.’”

It is recorded by Abū Dāwūd (81–82) and by Aḥmad (3/408–409); the latter, however, mentions the takbīr only twice at the beginning. Its chain is likewise acceptable.

Al-Tirmidhī (1/366)—this is his wording—and al-Nasāʾī (103) also transmit it through the route of Bishr b. Maʿādh: “Ibrāhīm b. ʿAbd al-ʿAzīz b. ʿAbd al-Malik b. Abī Maḥdhūrah narrated to us, saying, ‘My father and my grandfather both related to me from Abū Maḥdhūrah that the Messenger of Allah ﷺ seated him beside him and dictated the adhān to him phrase by phrase.’” Ibrāhīm said, “It is exactly like our adhān.” Bishr added, “So I said to him, ‘Repeat it for me,’ and he described the adhān with the tarjīʿ (the two-stage, low-voice then loud-voice repetition of the testimony).”

This isnād is sound, and al-Tirmidhī said—
