Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn, from Ali ibn al-Hakam from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “Abu Ja’far (a.s.), was asked about burping if it invalidates the fast. He (the Imam) said, ‘No, it does not invalidate one’s fast.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (6/287))
