Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 38
وَ رَوَى اَلْقَاسِمُ بْنُ مُحَمَّدٍ اَلْجَوْهَرِيُّ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ قَالَ: سَأَلْتُهُ عَمَّنْ قَالَ وَ اَللَّهِ ثُمَّ لَمْ يَفِ بِهِ قَالَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ "كَفَّارَتُهُ إِطْعَامُ عَشَرَةِ مَسَاكِينَ مُدّاً مُدّاً دَقِيقٍ أَوْ حِنْطَةٍ أَوْ تَحْرِيرُ رَقَبَةٍ أَوْ صِيَامُ ثَلاَثَةِ أَيَّامٍ مُتَوَالِيَةٍ إِذَا لَمْ يَجِدْ شَيْئاً".
Al-Qasim ibn Muhammad al-Jawhari narrated from Ali ibn Abi Hamzah, who said: I asked him about someone who said: "By Allah سبحانه وتعالى," and then did not fulfill it. Abu Abdillah عليه السلام said: "Its expiation is feeding ten needy people with a measure (mudd) each of flour or wheat, or freeing a slave. If he cannot find any of these, then he must fast for three consecutive days."
