A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid, from Muhammad ibn Ali from al-Husayn ibn Mukhariq abu Junadah al-Siluwliy from abu Hamzah who has said the following: “Abu Ja’far (a.s.), has narrated from his father who has narrated this Hadith.

’The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, “If one fasts during the month of Sha’ban, it will be a cleansing for him, from all zallah (a slip), wasmah and badirah.’” I (abu Hamzah) then asked, ‘What is wasmah?’ He replied, ‘It is swearing and a vow for unlawful cause.’ I asked, ‘What is badirah?’ He replied, ‘It is swearing when one is angry; repenting for it is regretting.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/258))
