Chapter on Fasting Shaban

And from him, from several of our companions, from Ahmad ibn Muhammad ibn Khalid, from Muhammad ibn Ali, from al-Husayn ibn Mukhariq and Abu Junadah al-Saluli, from Abu Hamzah, from Abu Ja’far عليه السلام, peace be upon him, from his father عليه السلام, peace be upon him: The Messenger of Allah سبحانه وتعالى, blessings of Allah سبحانه وتعالى be upon him and his family, said: ‘Whoever fasts Shaban, it will be for him a purification from every slip (of sin), stain (wasmah), and rash utterance (badirah).’” Abu Hamzah said: “So I asked to Abu Ja’far عليه السلام, ‘What is the stain (wasmah)?’” Imam عليه السلام said: “An oath in disobedience, and there is no vow in disobedience.” So I (narrator) asked: “What is the rash utterance (badirah)?” Imam عليه السلام said: “An oath at the time of anger, and repentance from it is at the time of regret.”
