Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah who has narrated the following: “I once asked abu ‘Abd Allah (a.s.), about the expiation because of oath. He (the Imam) said, ‘It is to set free a slave or clothing with two clothes or feeding ten destitute persons.

Whichever of the three he chooses is sufficient, and if he cannot find any of them, then it is three consecutive days of fasting and in feeding ten destitute persons: it is one mud (a certain measurement) for everyone.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (4/337))
