Abū ʿAbd al-Raḥmān said: I know of no one who mentioned al-Aswad in this ḥadīth except Zāʾidah.

3355 — Aḥmad ibn Sulaymān informed us, saying: Yazīd narrated to us, saying: Sufyān narrated to us, from Manṣūr, from Ibrāhīm, from ʿAlqamah, from ʿAbd Allāh, that a case was brought to him concerning a woman whom a man had married, then he died leaving her without having specified a dowry for her, and without having consummated the marriage with her. They came to him repeatedly for nearly a month, and he did not give them a ruling. Then he said: I hold that she is entitled to the dowry of women of her standing — neither diminished nor increased — and she is entitled to the inheritance, and she must observe the waiting period. Then Maʿqil ibn Sinān al-Ashjaʿī testified that the Messenger of Allāh ﷺ ruled in the case of Barwaʿ bint Wāshiq just as you have ruled.

============================================
The ḥadīth will also come via the chain of Sufyān al-Thawrī, from Manṣūr ibn al-Muʿtamir, with it, without mentioning al-Aswad, under numbers (3355), (3357), and (3524). And via the chain of al-Shaʿbī, from ʿAlqamah ibn Qays alone, with it, under number (3358). And via the chain of al-Shaʿbī, from Masrūq, from Ibn Masʿūd, with it, under number (3356).

His saying: "lā waks" means: no reduction from it, and "lā shaṭaṭ" means: no increase upon it; its origin is injustice and transgression. "Barwaʿ" is with kasrah on the bāʾ, and fatḥ on it has also been permitted; it is said that kasrah is [the pronunciation] among the ḥadīth scholars, while fatḥ is more well-known among the linguists.

(1) In (R): in a ḥadīth like this.
(2) It is mentioned in al-Dāraquṭnī's ʿIlal 8/49 that Sufyān al-Thawrī and Jaʿfar al-Aḥmar both narrated it from Manṣūr, from Ibrāhīm, from ʿAlqamah and al-Aswad, with it, so they also added al-Aswad in it — and Allāh knows best.
(3) Its chain is sound; Yazīd is Ibn Hārūn, and Sufyān is al-Thawrī. It is in al-Sunan al-Kubrā under number (5490).
Also recorded by Aḥmad (15943) and (18466), Abū Dāwūd (2115), and al-Tirmidhī following (1145) via the chain of Yazīd ibn Hārūn, with this chain of transmission; Yazīd ibn Hārūn was paired with ʿAbd al-Raḥmān ibn Mahdī in Abū Dāwūd's narration, and with ʿAbd al-Razzāq in al-Tirmidhī's, who said: The ḥadīth of Ibn Masʿūd is a ḥasan ṣaḥīḥ ḥadīth, and it has been narrated from him through multiple paths, and the practice is upon this according to some scholars among the Companions of the Prophet ﷺ and others, and al-Thawrī, Aḥmad, and Isḥāq hold this view… See the rest of his statement.
It will also come via the chain of ʿAbd al-Raḥmān ibn Mahdī, from Sufyān al-Thawrī, with it, under number (3357), and see =
