As for the hadith of Abū al-Dardāʾ, three narrators transmitted it from him:

The first was Abū ʿUmar al-Ṣīnī, from whom a number of narrators transmitted it. Al-Nasāʾī narrated it in ʿAmal al-Yawm wa-l-Laylah (149), as did ʿAbd al-Razzāq (3187), Ibn Abī Shaybah (10/235), and al-Ṭabarānī in al-Duʿāʾ (708), through al-Thawrī, from ʿAbd al-ʿAzīz ibn Rafīʿ, from him.

Al-Nasāʾī (150 and 151), Ibn Abī Shaybah (10/235), Aḥmad (6/446), Ibn al-Jaʿd in his Musnad (160), and—through Ibn al-Jaʿd—al-Mizzī in al-Tahdhīb (34/111), as well as al-Ṭabarānī in al-Duʿāʾ (710 and 711), narrated it through Shuʿbah and Mālik ibn Mighwal, from al-Ḥakam, from him.

Al-Ṭabarānī also narrated it (712) through Maymūn ibn Abī Shabīb, from him.

Likewise, al-Ṭabarānī narrated it (713) through Yūnus ibn Khabbāb, from him.

The second was Abū Ṣāliḥ. Al-Nasāʾī (147), Ibn Abī Shaybah (13/453), and al-Ṭabarānī in al-Duʿāʾ (709) narrated it through Abū al-Aḥwaṣ, from ʿAbd al-ʿAzīz ibn Rafīʿ, from him.

Al-Ṭayālisī narrated it (1235, according to its arrangement) through Sallām, from ʿAbd al-ʿAzīz, from him.

Ibn Abī Shaybah (13/453) and al-Ismāʿīlī—and through al-Ismāʿīlī, al-Ḥāfiẓ Ibn Ḥajar in al-Taghlīq (5/143)—narrated it through Jarīr, from ʿAbd al-ʿAzīz, from him.
