and al-Bayhaqī identified another flaw, saying: "It was narrated by Maḥmūd ibn Khālid from al-Walīd, from Ibn Jurayj, from ʿAmr ibn Shuʿayb, from his grandfather, from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam), without mentioning his father." This is what he said, and perhaps it is a version that occurred to him. Otherwise, al-Nasāʾī narrated it from him like the narration of the group from al-Walīd, saying after it: "Maḥmūd ibn Khālid informed us, saying: al-Walīd narrated to us from Ibn Jurayj, from ʿAmr ibn Shuʿayb, from his father, from his grandfather, exactly the same." As for al-Dāraquṭnī, he identified another flaw, saying: "No one narrated it from Ibn Jurayj with a connected chain except al-Walīd ibn Muslim, while others narrated it from Ibn Jurayj from ʿAmr ibn Shuʿayb as a mursal narration from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam)." I say: This does not harm [the narration] because al-Walīd is trustworthy and reliable; the flaw is only the ʿanʿanah as we have explained. The ḥadīth has supporting evidence from the narration of ʿAbd al-ʿAzīz ibn ʿUmar ibn ʿAbd al-ʿAzīz: "Some of the delegates who came to my father told me that the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said: 'Any doctor who practices medicine on a people without prior knowledge of medicine, and causes harm, is liable.'" ʿAbd al-ʿAzīz said: "It is not harm; rather, it is cutting veins, cauterization, and branding." I say: Its isnād is good except that it is mursal with an unknown transmitter, but the ḥadīth is good when considering both paths. And Allāh knows best.

- "I pledge allegiance to you to worship Allāh, establish prayer, give zakāh, advise the Muslims sincerely, and separate from the polytheist." It was recorded by al-Nasāʾī (2/183), al-Bayhaqī (9/13), and Aḥmad (4/365)
