The wording is that of ʿUbaydullāh.

2110 – ʿImrān ibn Yazīd ibn Khālid informed us, saying: Shuʿayb narrated to us, saying: Ibn Jurayj informed me, saying: ʿAṭāʾ informed me, saying:

I heard Ibn ʿAbbās narrating to us, saying: The Messenger of Allah, peace and blessings be upon him, said to a woman from the Anṣār: "When Ramaḍān comes, perform ʿUmrah in it, for a ʿUmrah in it is equivalent to a Ḥajj." (1)

--------------------------------------------
= Al-Ḥasan al-Baṣrī, by his hearing from Abū Bakrah, and it is (2704) and (3746) and (7109). Yaḥyā ibn Saʿīd: he is al-Qaṭṭān. And ʿUbaydullāh ibn Saʿīd: he is Abū Qudāmah al-Sarakhsī. It is in "Al-Sunan al-Kubrā" under number (2430).

And Aḥmad (20406), Abū Dāwūd (2415), and Ibn Ḥibbān (3439) also narrated it via the chain of Yaḥyā ibn Saʿīd with this isnād.

And Aḥmad (20416) and (20488) narrated it via the chain of Qatādah, from al-Ḥasan, with it.

Al-Sindī said: His statement: "Let none of you say: I fasted Ramaḍān" — the mention of "Ramaḍān" without "the month of" is evidence that it is permissible to use it in this manner, and the prohibition does not refer to that, but rather refers to attributing the fast to oneself entirely within it, while its acceptance before Allah is in a place of peril.

His statement: "There must be heedlessness" — meaning: he disobeys in a state of heedlessness in a manner that is not befitting of fasting, so how can he then claim the fast for himself?

(1) Its isnād is sound. Shuʿayb: he is Ibn Isḥāq ibn ʿAbd al-Raḥmān al-Umawī, and Ibn Jurayj: he is ʿAbd al-Malik ibn ʿAbd al-ʿAzīz, and his narration from ʿAṭāʾ — who is Ibn Abī Rabāḥ — is treated as connected, and moreover he explicitly stated that he narrated from him in this narration. It is in "Al-Sunan al-Kubrā" under number (2431).

And Aḥmad (2025), al-Bukhārī (1782), Muslim (1256): (221), the author in "Al-Kubrā" (4209), and Ibn Ḥibbān (3700) narrated it via various chains from Ibn Jurayj, with this isnād.

And it was narrated in full and in expanded form by Aḥmad (2808) and (2809), al-Bukhārī (1863), Muslim (1256): (222), and Ibn Mājah (2994) via various chains from ʿAṭāʾ with it. The woman was named in the narration of al-Bukhārī and Muslim: Umm Sinān al-Anṣāriyyah.

And Ibn Ḥibbān (3699) narrated it via the chain of Yaʿqūb ibn ʿAṭāʾ, from ʿAṭāʾ, with it. In it, the woman is named Umm Sulaym, but Yaʿqūb ibn ʿAṭāʾ is weak.=
