I say: This is an authentic chain of transmission; all its narrators are trustworthy and are narrators of Muslim. Ahmad also narrated it (2/278 and 317): “ʿAbd al-Razzāq narrated to us,” with similar wording. (See Addendum no. 231/2.) Ibn Mājah also narrated it (2114): “Sufyān ibn Wakīʿ narrated to us; Muḥammad ibn Ḥumayd al-Maʿmarī narrated to us, from Maʿmar,” with the same wording; and through ʿIkrimah, from Abū Hurayrah, from the Prophet, peace and blessings be upon him, with similar wording.

Al-Maʿmarī is trustworthy and one of Muslim’s narrators, but the narrator reporting from him is weak. However, he was not alone in narrating it, for al-Ḥākim (4/301) and al-Ḥarbī also narrated it through Yaḥyā ibn Ṣāliḥ al-Wuhāẓī: Muʿāwiyah ibn Sallām narrated to us, from Yaḥyā ibn Abī Kathīr, from ʿIkrimah, with the wording: “Whoever stubbornly persists in an oath concerning his family incurs a grave sin; expiation will not avail him.” Al-Ḥākim said: “It is authentic according to al-Bukhārī’s criteria,” and al-Dhahabī concurred.

Al-Ḥarbī said: “His saying, ‘stubbornly persists,’ is derived from obstinacy in an oath: repeating it, reinforcing it, and adhering to it. That is, if his oath is made in obstinacy and insistence, without an exception, then he bears a grave sin; expiation does not absolve him of the sin he has incurred. Expiation applies only to one whose oath was not made with such insistence or obstinacy, and who regrets it, then does what he had sworn against and offers expiation.” (See Addendum no. 231/16.)

1230 — “When a man embraces Islam, he has greater right to his land and wealth.”

Ahmad narrated it (4/310) through Abān ibn ʿAbd Allāh al-Bajalī, who said: “My paternal uncles related to me from their grandfather, Ṣakhr ibn Aylah: ‘Some men of Banū Sulaym fled from their land when Islam came. I took possession of it, and then they embraced Islam. They brought a dispute against me concerning it before the Prophet, peace and blessings be upon him, so he returned it to them and said’”—and then cited the above wording.

I say: This chain is good, Allah the Exalted willing. There is disagreement regarding this Abān, though the majority considered him trustworthy. Al-Dhahabī said: “His hadith is good.” Al-Ḥāfiẓ said: “Truthful, though there is some weakness in his retention.”
