Hadith 8398- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ أَبِي حَمْزَةَ الثُّمَالِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَمَّنْ قَالَ وَاللهِ ثُمَّ لَمْ يَفِ فَقَالَ أَبُو عَبْدِ اللهِ (عَلَيْهِ السَّلام) كَفَّارَتُهُ إِطْعَامُ عَشَرَةِ مَسَاكِينَ مُدّاً مُدّاً مِنْ دَقِيقٍ أَوْ حِنْطَةٍ أَوْ تَحْرِيرِ رَقَبَةٍ أَوْ صِيَامُ ثَلاثَةِ أَيَّامٍ مُتَوَالِيَاتٍ إِذَا لَمْ يَجِدْ شَيْئاً مِنْ ذَا.
8. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from abu Hamzah al-Thumaliy who has narrated the following: “I once asked abu ‘Abd Allah (a.s.), about the case of a man who has said by Allah, but has not remained firm about it. He (the Imam) (a.s.), said, ‘The Kaffarah (expiation) for it is to feed ten destitute people, one mud (a certain measurement) to each one of flour or wheat, or free a slave, or fast for three consecutive days if he cannot find the other remedies.’”
