This chain is acceptable for corroboration. All its narrators are trustworthy narrators of Muslim, except al-Hijrī, whose name was Ibrāhīm ibn Muslim and whose hadith is somewhat weak. Al-Ḥākim also transmitted it through his route (1/555) and said: “Its chain is authentic.” Al-Dhahabī countered: “Ibrāhīm is weak.”

It also has another corroborating report, which al-Ḥākim transmitted (1/566) through ʿĀṣim ibn Abī al-Najūd, from Abū al-Aḥwaṣ, with wording similar to the hadith of ʿAṭāʾ. He said: “Its chain is authentic,” and al-Dhahabī concurred.

Ibn al-Mubārak also transmitted it in al-Zuhd (808), attributed to the Companion: “Shurayk informed us, from Abū Isḥāq, from Abū al-Aḥwaṣ,” with the same wording. Shurayk had a poor memory.

I say: This is an authentic chain according to Muslim’s criteria. Abū Ayyūb was al-Marāghī al-Azdī of Basra. Al-Būṣīrī said in al-Zawāʾid (54/1):
