in "al-Zuhd" (p. 238/2), al-Tirmidhī (2/42-43), al-ʿUqaylī in "al-Ḍuʿafāʾ" (408), Ibn ʿAdī in "al-Kāmil" (323/1), Abū Nuʿaym in "Akhbār Aṣbahān" (1/308), and al-Bayhaqī in "al-Dalāʾil" (vol. 2) through various chains from Mūsá ibn ʿUbaydah from ʿAbd Allāh ibn Dīnār from ʿAbd Allāh ibn ʿUmar who said: The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said: and he mentioned it. al-Tirmidhī said: "It is a strange ḥadīth, and Abū Muʿāwiyah narrated it from Yaḥyá ibn Saʿīd al-Anṣārī. Muḥammad ibn Ismāʿīl al-Wāsiṭī informed us of this, saying: Abū Muʿāwiyah narrated from Yaḥyá ibn Saʿīd from ʿAbd Allāh ibn Dīnār from Ibn ʿUmar from the Prophet (ṣallá Allāhu ʿalayhi wa-sallam) similarly. There is no known origin for Abū Muʿāwiyah's ḥadīth from Yaḥyá ibn Saʿīd; the known ḥadīth is that of Mūsá ibn ʿUbaydah. Mālik ibn Anas also narrated this ḥadīth from Yaḥyá ibn Saʿīd in a mursal form and did not mention it from ʿAbd Allāh ibn Dīnār from Ibn ʿUmar." I say: Mūsá ibn ʿUbaydah is weak, but the corroboration by Yaḥyá ibn Saʿīd supports the authenticity of his ḥadīth. As for al-Tirmidhī's statement that there is no origin for it from him, I see it as an apparent exaggeration because the chain to him is authentic. Abū Muʿāwiyah is trustworthy, among the narrators of the two Shaykhs, and Muḥammad ibn Ismāʿīl al-Wāsiṭī is a reliable memorizer, as the ḥāfiẓ said. Mālik often narrates in a mursal form what is known to have a connected chain, as is not hidden from those knowledgeable in this noble field. Moreover, it seems there is a difference of opinion regarding Mālik, as Naṣr al-Maqdisī reported it in (session 347 of "al-Amālī") through the route of al-Qaʿnabī ʿAbd Allāh ibn Maslamah ibn Qaʿnab, who said: Mālik informed us from Yaḥyá ibn Saʿīd from Yaḥnas, the freedman of al-Zubayr, in a marfūʿ form, except that he said: "He set some of them over others." So he added Yaḥnas to the chain. Likewise, it was reported by al-Dānī in "al-Fitan" (188/1-2) and al-Bayhaqī in "Dalāʾil al-Nubuwwah" (vol. 2) through another route from Yaḥyá ibn Saʿīd. Al-Faraj ibn Faḍālah disagreed with them, saying: from Yaḥyá ibn Saʿīd al-Anṣārī, raising it
