"Whoever swears an oath to sever family ties or to do something improper, his righteousness is to not fulfill it." It was recorded by Ibn Mājah (1/648) from Ḥārithah ibn Abī al-Rijāl from ʿAmrah from ʿĀʾishah as a marfūʿ ḥadīth. I say: This isnād is weak, and its narrators are trustworthy except for Ḥārithah, who is weak as stated by al-Ḥāfiẓ, and al-Būṣīrī followed him (130/2). However, I found a strong supporting narration for the ḥadīth from Abū Maʿbad from Ibn ʿAbbās, raised [to the Prophet], who said: "Whoever swears an oath to sever family ties or commit a sin and then breaks it, that is an expiation for him." It was recorded by al-Ṭaḥāwī in "Mushkil al-Āthār" (1/287): narrated to us by Bakkār, narrated to us by Abū Aḥmad Muḥammad ibn ʿAbd Allāh ibn al-Zubayr al-Asadī al-Kūfī, narrated to us by Muḥammad ibn Sharīk from Sulaymān al-Aḥwal from him. I say: This isnād is authentic, and all its narrators are trustworthy from the men of "al-Tahdhīb," except for Bakkār - he is Ibn Qutaybah al-Thaqafī al-Bakrāwī, Abū Bakrah the Ḥanafī jurist from Basra. Al-Suyūṭī said in "Ḥusn al-Muḥāḍarah" (1/263): "Abū ʿAwānah narrated from him in his 'Ṣaḥīḥ' and Ibn Khuzaymah, and al-Mutawakkil appointed him as judge in Egypt in the year 246 AH, and he has reports on justice, chastity, integrity, and piety. He died in the year 270 AH." I say: Al-Dhahabī mentioned him among the teachers of al-Ṭaḥāwī in this biography, and even cited another ḥadīth from his narration from Bakkār ibn Qutaybah, narrated to us by Abū Aḥmad, narrated to us by Sufyān... I say: This is because it is possible that Bakkār in this ḥadīth is actually Ibn Sahl al-Dimyāṭī, the client of Banū Hāshim, as al-Dhahabī mentioned among those who narrated from him to al-Ṭaḥāwī, and al-Dimyāṭī is weak as he said
