Ahmad recorded it, stating: “ʿAbd al-Razzaq narrated to us—Sufyan narrated to us—from ʿAwn ibn Abi Juḥayfah, from his father …”
Al-Hakim also transmitted it from Ahmad, and al-Tirmidhi from Maḥmūd ibn Ghaylān, both through the line of transmission that goes back to ʿAbd al-Razzaq.
Al-Hakim then cited it by way of Ibrāhīm ibn ʿUyaynah, from al-Thawri and Mālik ibn Miġwal, from ʿAwn ibn Abi Juḥayfah, with wording to the same effect. He remarked:
“Both Shaykhān (al-Bukhari and Muslim) agreed on recording the report of Mālik ibn Miġwal and ʿUmar ibn Zāʾidah, from ʿAwn ibn Abi Juḥayfah, from his father, concerning the Prophet’s ﷺ encampment at al-Abṭaḥ. However, they did not mention putting the fingers in the ears or turning while giving the adhān. The report is nevertheless authentic according to their criteria, and both practices are established Sunnah.”
Al-Dhahabi endorsed his judgment, and the matter stands as they both affirmed.
This shows that ʿAbd al-Razzaq was not the sole transmitter to mention inserting the two fingers and turning during the call to prayer; he was followed in this by al-Ḥusayn ibn Jaʿfar—namely, al-Ḥusayn ibn Manṣur ibn Jaʿfar al-Nīsābūri, a trustworthy jurist—and by Ibrāhīm ibn ʿUyaynah (so in the original; the correct form is ʿUyaynah, with a voiced dental fricative, a yāʾ, and a nūn). He was the brother of Sufyan ibn ʿUyaynah and is deemed reliable, though prone to error, as stated in Taqrīb.
He was also followed by Muʾammal ibn Ismāʿīl, from Sufyan. Abū ʿAwānah reproduced the narration in his Ṣaḥīḥ in similar terms, as recorded in Naṣb al-Rāyah and Fatḥ al-Bārī, and Ibn Khuzaymah transmitted it as well, according to Talkhīṣ. He added: “Abū Nuʿaym also narrated it …”
