Al-Zaylaʿī likewise says in his Takhrīj Aḥādīth al-Karāhiyyah:
“I have remarked: this report is singular in the narration of Abū Hurayrah, and it has already appeared through the line of ʿAlī in al-Dāraquṭnī, but it is weak.”

We have yet to address the chain of transmission for the report of Abū Mūsā, so we say: all of its transmitters are trustworthy and are among the narrators relied upon by the Ṣaḥīḥs, except for ʿAlī ibn Shaybah and Ḥakīm al-Athram.

As for the first, he is ʿAlī ibn Shaybah ibn al-Ṣalt ibn ʿUṣfūr, Abū al-Ḥasan al-Sudūsī, their client—also known as Abū Yaʿqūb ibn Shaybah—a Basran who lived in Baghdad for a period before relocating to Egypt, where he remained. ʿAbd al-ʿAzīz ibn Aḥmad al-Ghāfiqī and other Egyptian scholars narrated sound ḥadīths from him. He died in 272 AH. So states Tārīkh Baghdād, with slight adaptation.

Regarding the other, al-Nasāʾī said: “There is no harm in him.” Ibn Ḥibbān listed him in al-Thiqāt, while al-Taqrīb notes: “He is somewhat soft.”

A report from ʿAlī ibn Abī Ṭālib—may Allah be pleased with him—mentions: “Hamzah looked at the Messenger of Allah ﷺ, then lifted his gaze and looked at his knees, then lifted it again and looked at his navel …” and so forth. Al-Bukhārī and Muslim recorded it, and Ibn Ḥazm and al-Ṭaḥāwī transmitted it from them.
