ʿAbd Allāh ibn ʿUbayd Allāh al-Hāshimī is from the generation of ʿAbd Allāh ibn ʿUbayd Allāh ibn ʿAbbās ibn ʿAbd al-Muṭṭalib al-Hāshimī, and he is considered reliable among the scholars of the two Shaykhs [al-Bukhārī and Muslim]. However, they did not mention any narration from him about ʿAbd Allāh ibn ʿUkaym, nor did they mention Ibrāhīm — meaning al-Nakhaʿī — among those who narrated from him. Haytham ibn Khālid, who is al-Muṣīṣī, was mentioned by al-Dhahabī in "al-Ḍuʿafāʾ" and he said: "al-Dāraquṭnī said: Weak." al-Ḥāfiẓ confirmed this in "al-Tahdhīb" and decisively stated his weakness in "al-Taqrīb." However, it was narrated by Shabīb ibn Saʿīd from Shuʿbah from al-Ḥakam from ʿAbd al-Raḥmān ibn Abī Laylá from ʿAbd Allāh ibn ʿUkaym who said: The letter of the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) came to us while we were in the land of Juhaynah: "I had permitted you the use of the hide of carrion and its tendons, so do not benefit from any tendon or hide." Ibn ʿAdī included it in the biography of this Shabīb in "al-Kāmil" (4/1347) and al-Ṭabarānī also, as mentioned in "Talkhīṣ al-Ḥabīr" (1/47), said: "Its chain is reliable, and it was corroborated by Faḍālah ibn al-Mufaḍḍal with al-Ṭabarānī in (al-Awsaṭ)." I said: Faḍālah's wording of the ḥadīth differs from this as it is worded: "I had permitted you the use of the skins of carrion, so do not benefit from the carrion by its skin or tendon." The skin was mentioned in both places instead of the hide, and what is preserved (is the hide), which is the skin before tanning. This is how a group narrated it from Shuʿbah, and it is included in "al-Irwāʾ" (number 38). Faḍālah ibn al-Mufaḍḍal, Ibn Abī Ḥātim said (3/2/79) about him from his father:
