(he lowers his voice for these two testimonies, then raises it again and repeats them—this is the tarjīʿ):

This wording is found in the ḥadith of Abū Maḥdhūrah (may Allah be pleased with him): the Prophet ﷺ taught him an adhān of nineteen words and an iqāmah of seventeen.

It was recorded by Abū Dāwūd (82), al-Nasāʾī (103), al-Tirmidhī (367), al-Dārimī (271), Ibn Mājah (242–243), al-Ṭaḥāwī (1/78), al-Dāraqutnī (87, 88), Ibn Hazm (3/150), al-Ṭayālisī (193), and Aḥmad (3/409; 6/401), all of them through the chain of Ḥammām, who said: ʿĀmir al-Aḥwal narrated to us; he said: Makḥūl informed me that ʿAbd Allāh b. Muḥayriz related it to him—from Abū Maḥdhūrah.

Abū Dāwūd, Ibn Mājah, al-Dāraqutnī, al-Ṭaḥāwī, Aḥmad, and Ibn Hazm went on to cite the actual wording of the adhān.

Then al-Tirmidhī said:
