I then said: Ibn al-Turkmanī took issue with this and remarked:
“I say: He was not the only one to narrate it; rather, ʿAbd al-Malik ibn Muʿādh al-Nuṣaybī also corroborated him, transmitting it in the same manner from al-Darāwardī. Abū ʿUmar recorded it as such in his two works, al-Tamhīd and al-Istidhkār.”
I continued: It is apparently because of this corroboration that al-Ḥākim then declared, “Authentic according to the criteria of Muslim,” a judgement with which al-Dhahabī agreed. Were it not for that corroboration, the ḥadīth would not meet Muslim’s criteria, for ʿUthmān ibn Muḥammad is not among his narrators—and, beyond that, he has been criticized. Al-Dāraqutnī said, “He is weak,” and ʿAbd al-Ḥaqq said, “Error predominates in his narrations.” Even so, his report might be strengthened by this corroboration from al-Nuṣaybī, though the latter’s status is unknown, as Ibn al-Qaṭṭān pointed out and al-Dhahabī concurred. Yet al-Nuṣaybī likewise does not belong to Muslim’s narrator-pool, so the ḥadīth is still not on Muslim’s criteria. Nevertheless, scholars often show leniency with a corroborated report that they do not extend to an isolated chain; hence they may say of the former that it is “according to Muslim’s criteria,” taking into account only the transmitters above the corroborators, as is well known.
For this reason we find al-Ḥāfiẓ Ibn Rajab, in his commentary on al-Nawawī’s Forty Ḥadīths (p. 219), did not fault the ḥadīth because of this ʿUthmān or on account of al-Nuṣaybī’s corroboration. Rather, he declared it defective on account of their teacher, saying after al-Bayhaqī’s aforementioned statement:
“Ibn ʿAbd al-Barr said: There is no variant from Mālik except that he transmitted this ḥadīth in mursal form, and there is no chain for it that is sound. He then produced it with the isnād of ʿAbd al-Malik ibn Muʿādh al-Nuṣaybī from al-Darāwardī in connected form. Al-Darāwardī—Imām Aḥmad regarded whatever he narrated from memory as weak and paid it no heed, and without a doubt Mālik’s judgment takes precedence over his.”
