...from the chain of transmission, one narrator [is missing]. If the one omitted is Umm al-Dardā', then the chain is interrupted (munqaṭiʿ); if it is Abū al-Dardā', then it is mursal, because Umm al-Dardā' is a Tābiʿiyyah. And God Almighty knows best.

Al-Dūlābī also narrated it in "al-Kunā" 2/38 via the route of ʿAlī ibn ʿAyyāsh, and Ibn ʿAbd al-Barr in "al-Tamhīd" 5/282 via the route of Sulaymān ibn ʿAbd al-Raḥmān al-Dimashqī — both from Ismāʿīl ibn ʿAyyāsh, from Thaʿlabah ibn Muslim al-Khathʿamī, from Abū ʿImrān al-Anṣārī, from Abū al-Dardā'.

Al-Ṭabarānī also narrated it in "al-Kabīr" 24/(649) via the route of ʿAlī ibn ʿAyyāsh, from Ismāʿīl ibn ʿAyyāsh, from Thaʿlabah ibn Muslim, from Abū ʿImrān Sulaymān ibn ʿAbd Allāh, from Umm al-Dardā'.

Supporting it — apart from his statement: "And do not treat yourselves with what is forbidden" — is the ḥadīth of Usāmah ibn Sharīk mentioned previously by the author under number (3855). Its chain of transmission is sound (ṣaḥīḥ).

The ḥadīth of ʿAbd Allāh ibn Masʿūd is found in Aḥmad (3578) and (3922), Ibn Ḥibbān (6062), and others. Its chain of transmission is sound.

The ḥadīth of Abū Hurayrah is found in al-Bukhārī (5678), Ibn Mājah (3439), and al-Nasā'ī in "al-Kubrā" (7513).

The ḥadīth of Anas is found in Aḥmad (12596) and others. Its chain of transmission is sound.

The ḥadīth of Jābir ibn ʿAbd Allāh is found in Aḥmad (14597), Muslim (2204), and al-Nasā'ī in "al-Kubrā" (7514).

The ḥadīth of a man from the Anṣār is found in Aḥmad (23156). Its chain of transmission is sound.

Supporting his statement: "And do not treat yourselves with what is forbidden" is the ḥadīth of Abū Hurayrah mentioned previously by the author under number (3870), and its wording is: "The Messenger of God, may God bless him and grant him peace, forbade treatment with foul/unlawful medicine."

The ḥadīth of Umm Salamah is found in Aḥmad's "al-Ashribah" (159), Ibn Abī al-Dunyā in "Dhamm al-Muskir" (12), Abū Yaʿlā (6966), Ibn Ḥibbān (1391), and al-Ṭabarānī in "al-Kabīr" 23/(749). Its chain of transmission is good (ḥasan) when considered with supporting witnesses.

The ḥadīth of ʿAbd Allāh ibn Masʿūd as a mawqūf narration is found in ʿAbd al-Razzāq (17097) and (17102), Ibn Abī Shaybah 8/23 and 130, Aḥmad in "al-Ashribah" (130) and (133), al-Ṭaḥāwī in "Sharḥ Maʿānī al-Āthār" 1/108, Abū al-Qāsim al-Baghawī in "al-Jaʿdiyyāt" (190), and al-Ṭabarānī in "al-Kabīr" (9714)–(9717). Al-Bukhārī also attached it in his "Ṣaḥīḥ" before ḥadīth (5614) in a definitive form. Its chain of transmission is sound.
