Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 2|Chapter 7
رَوَى أَبُو حَمْزَةَ اَلثُّمَالِيُّ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: «مَنْ صَامَ شَعْبَانَ كَانَ لَهُ طَهُوراً مِنْ كُلِّ زَلَّةٍ وَ وَصْمَةٍ وَ بَادِرَةٍ» وَ قَالَ أَبُو حَمْزَةَ فَقُلْتُ لِأَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ مَا اَلْوَصْمَةُ قَالَ «اَلْيَمِينُ فِي اَلْمَعْصِيَةِ وَ اَلنَّذْرُ وَ لاَ نَذْرَ فِي اَلْمَعْصِيَةِ» قُلْتُ فَمَا اَلْبَادِرَةُ قَالَ «اَلْيَمِينُ عِنْدَ اَلْغَضَبِ وَ اَلتَّوْبَةُ مِنْهَا اَلنَّدَمُ عَلَيْهَا ».
Abu Hamzah al-Thumali narrated from Abu Ja‘far (Imam Muhammad ibn Ali Al-Baqir عليه السلام), who said: "Whoever fasts during Sha‘ban, it will purify him from every slip, stain, and impulsive act." Abu Hamzah said: "I asked Abu Ja‘far عليه السلام: 'What is the stain (al-wasmah)?' Imam عليه السلام said: 'An oath made for disobedience or a vow, for there is no vow in disobedience.' I asked: 'What is the impulsive act (al-badirah)?' Imam عليه السلام said: 'An oath made in anger, and its repentance is to feel regret for it.'"
