٥- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ فَضَالَةَ بْنِ أَيُّوبَ عَنِ ابْنِ مُسْكَانَ عَنْ حَمْزَةَ بْنِ حُمْرَانَ عَنْ زُرَارَةَ قَالَ قُلْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَيُّ شَيْ‏ءٍ الَّذِي فِيهِ الْكَفَّارَةُ مِنَ الأيْمَانِ فَقَالَ مَا حَلَفْتَ عَلَيْهِ مِمَّا فِيهِ الْبِرُّ فَعَلَيْهِ الْكَفَّارَةُ إِذَا لَمْ تَفِ بِهِ وَمَا حَلَفْتَ عَلَيْهِ مِمَّا فِيهِ الْمَعْصِيَةُ فَلَيْسَ عَلَيْكَ فِيهِ الْكَفَّارَةُ إِذَا رَجَعْتَ عَنْهُ وَمَا كَانَ سِوَى ذَلِكَ مِمَّا لَيْسَ فِيهِ بِرٌّ وَلا مَعْصِيَةٌ فَلَيْسَ بِشَيْ‏ءٍ.
5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah ibn Ayyub from ibn Muskan from Hamzah ibn Humran from Zurarah who has narrated the following: “I once asked abu ‘Abd Allah , about the kind of oath that makes expiation obligatory. He (the Imam) said, ‘If you take an oath for doing something which is a virtuous deed, there is expiation if you do not do it. If you take an oath to do something which is an act of disobedience you do not owe anything if you did not do it; other than these which are not virtuous or of disobedience do not have any valid effect.’”
