2011 - رَوَى أَحْمَدُ بْنُ مُحَمَّدِ بْنِ أَبِي نَصْرٍ اَلْبَزَنْطِيُّ عَنْ أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ : فِي رَجُلٍ نَذَرَ عَلَى نَفْسِهِ إِنْ هُوَ سَلِمَ مِنْ مَرَضٍ أَوْ تَخَلَّصَ مِنْ حَبْسٍ أَنْ يَصُومَ كُلَّ يَوْمِ أَرْبِعَاءَ وَ هُوَ اَلْيَوْمُ اَلَّذِي تَخَلَّصَ فِيهِ فَعَجَزَ عَنْ ذَلِكَ لِعِلَّةٍ أَصَابَتْهُ أَوْ غَيْرِ ذَلِكَ فَمَدَّ اَللَّهُ عَزَّ وَ جَلَّ لِلرَّجُلِ فِي عُمُرِهِ وَ اِجْتَمَعَ عَلَيْهِ صَوْمٌ كَثِيرٌ مَا كَفَّارَةُ ذَلِكَ قَالَ «تَصَدَّقَ لِكُلِّ يَوْمٍ مُدّاً مِنْ حِنْطَةٍ أَوْ بِمُدِّ تَمْرٍ.
Hadith.2011 - Ahmad ibn Muhammad ibn Abi Nasr al-Bazanti narrated from Imam Abu al-Hasan al-Ridha 
regarding:
A man who vowed upon himself that if he were to recover from an illness or be released from imprisonment, he would fast every Wednesday—the same day he was released. However, due to an ailment or another reason, he was unable to fulfill this vow. Over time, many missed fasts accumulated. The man sought guidance on what expiation would be required for this.
The Imam replied: "He should give charity for each missed day, either with a mud (a measure) of wheat or a mud of dates."
