"truthful but makes mistakes." The ḥadīth was attributed by al-Ḥāfiẓ al-ʿIrāqī in "Takhrīj al-Iḥyāʾ" (2/324) to al-Nasāʾī only in "ʿAmal al-Yawm wa-al-Laylah" and he graded it as ḥasan.

"He had a donkey called: ʿUfayr." It was recorded by al-Ṭaḥāwī in "Mushkil al-Āthār" (1/478), Ibn Saʿd in "al-Ṭabaqāt" (1/492), and al-Ṭabarānī in "al-Kabīr" (3/71/1) through the route of Yazīd ibn ʿAṭāʾ Abū Isḥāq al-Hamdānī from Abū ʿUbaydah ibn ʿAbd Allāh ibn Masʿūd from his father, as a marfūʿ ḥadīth.

However, it is supported by the ḥadīth of Salamah ibn al-Faḍl: Muḥammad ibn Isḥāq narrated to me from Yazīd ibn Abī Ḥabīb from Marthad ibn ʿAbd Allāh al-Yaznī from ʿAbd Allāh ibn Zurayr al-Ghāfiqī from ʿAlī ibn Abī Ṭālib: "that the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) used to ride a donkey named ʿUfayr." It was recorded by Aḥmad (number 886). Its isnād is weak due to the ʿanʿanah of Ibn Isḥāq and the weakness of Salamah ibn al-Faḍl, as al-Ḥāfiẓ said: "truthful but makes many mistakes." As for Shaykh Aḥmad Shākir, he said in his commentary on "al-Musnad": "Its isnād is ṣaḥīḥ!" I say: This is due to his leniency, which he is known for, especially regarding his acceptance of the ʿanʿanah of Ibn..
