The latter part of it has an authentic corroborating report in the hadith of ʿAmr ibn al-ʿĀṣ, attributed to the Prophet, to similar effect; it is the hadith that follows.
An aʿṣam is one with a red beak and red legs, as stated in the following hadith. This is a figurative expression for how few women will enter Paradise, because this description is rare among crows.
1850 — “No women will enter Paradise except those among them who are like this crow among crows.”
Aḥmad narrated it (4/197 and 205), as did Abū Yaʿlā (349/1)—whose version contains the additional wording—from Ḥammād ibn Salamah, from Abū Jaʿfar al-Khaṭmī, from ʿUmārah ibn Khuzaymah, who said: While we were with ʿAmr ibn al-ʿĀṣ during Hajj or ʿUmrah, we came upon a woman wearing bracelets (1) and rings, who had stretched out her hand over the camel litter. He said: “While we were with the Messenger of Allah, peace and blessings be upon him, in this mountain pass, he said: ‘Look! Do you see anything?’ We said, ‘We see crows, among which is an aʿṣam crow with a red beak and red legs.’ The Messenger of Allah, peace and blessings be upon him, then said...” and he mentioned it.
Ibn Qutaybah also narrated it in Correction of Errors (53/1–2) through this route, as did al-Ḥākim (4/602) and Ibn ʿAsākir (13/245/1–2).
I say: This is an authentic chain of transmission. Al-Ḥākim’s statement, “Authentic according to Muslim’s criteria,” is erroneous—an error with which al-Dhahabī concurred—because this Abū Jaʿfar, whose name was ʿUmayr ibn Yazīd, was not narrated from by Muslim at all.
1851 — “The caliphate is among Quraysh, governance among the Anṣār, the call in Abyssinia, and emigration among the Muslims; and the Emigrants thereafter.”
