Ahmad ibn Muhammad has narrated from ibn Faddal from ibn Bukayr from Zurarah who has narrated the following: “I once asked abu Ja‘far (a.s.), about the case of a man who takes an oath very seriously not to buy for his family. He (the Imam) said, ‘He must buy for them and he does not owe anything because of his oath.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (24/319))
