Abū al-Faraj Ibn al-Jawzī (1) and Muḥammad ibn ʿAbd al-Wāḥid al-Maqdisī said:

“Muslim included his ḥadith in the Ṣaḥīḥ (2), and al-Bukhārī cited it as supporting evidence in his Ṣaḥīḥ.

Moreover, al-Tirmidhī pronounced it authentic through a chain that does not pass through al-Zuhrī (3), saying: ‘Ziyād ibn Ayyūb narrated to us; ʿAbbād ibn al-ʿAwwām narrated to us, from Sufyān ibn Ḥusayn, from Yūnus ibn ʿUbayd, from ʿAṭāʾ, from Jābir: “The Messenger of Allah ﷺ forbade al-muḥāqala (bartering grain that is still in the ear), al-muzābana (selling fresh produce for an estimated quantity of dry produce), al-mukhābara (share-cropping), and al-thunyā (withholding an undefined share) unless that share is clearly specified).”’ (4)

He then remarked, ‘This ḥadith is sound, authentic, and singular through this route from Yūnus ibn ʿUbayd, from ʿAṭāʾ, from Jābir.’

Imām Aḥmad’s silence about it after including it in his Musnad—and his deriving his legal view from it—is by itself sufficient proof that he regarded it as authentic.

Al-Ḥāfiẓ Abū Mūsā al-Madīnī (5) also stated: ‘Whatever Imām Aḥmad records in the Musnad is, in his judgment, authentic.’
