٣- عَنْهُ عَنْ سَعْدِ بْنِ سَعْدٍ عَنْ مُحَمَّدِ بْنِ الْقَاسِمِ بْنِ الْفُضَيْلِ عَنْ حَمْزَةَ بْنِ حُمْرَانَ عَنْ دَاوُدَ بْنِ فَرْقَدٍ عَنْ حُمْرَانَ قَالَ قُلْتُ لأبِي جَعْفَرٍ وَأَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) الْيَمِينُ الَّتِي تَلْزَمُنِي فِيهَا الْكَفَّارَةُ فَقَالا مَا حَلَفْتَ عَلَيْهِ مِمَّا للهِ فِيهِ طَاعَةٌ أَنْ تَفْعَلَهُ فَلَمْ تَفْعَلْهُ فَعَلَيْكَ فِيهِ الْكَفَّارَةُ وَمَا حَلَفْتَ عَلَيْهِ مِمَّا للهِ فِيهِ الْمَعْصِيَةُ فَكَفَّارَتُهُ تَرْكُهُ وَمَا لَمْ يَكُنْ فِيهِ مَعْصِيَةٌ وَلا طَاعَةٌ فَلَيْسَ هُوَ بِشَيْ‏ءٍ.
3. It is narrated from the narrator of the previous Hadith from Sa‘d ibn Sa‘d from Muhammad ibn al-Qasim ibn al-Fudayl from Hamzah ibn Humran from Dawud ibn Farqad from Humran who has narrated the following: “I once asked abu Ja‘far, and abu ‘Abd Allah, ‘Alayhim al-Salam, about the kind of oath for which I owe expiation. They said, ‘It is when you take an oath for an act in which there is obedience to Allah if you do it and you do not do it, then there is expiation on you. If you take an oath for an act in which there is disobedience to Allah then its expiation is not to do it. An oath about the act which is not an obedience or disobedience does not have any valid effect.’”
