1793 - وَ سَأَلَ عِيصُ بْنُ اَلْقَاسِمِ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : عَمَّنْ لَمْ يَصُمِ اَلثَّلاَثَةَ مِنْ كُلِّ شَهْرٍ وَ هُوَ يَشْتَدُّ عَلَيْهِ اَلصِّيَامُ هَلْ فِيهِ فِدَاءٌ فَقَالَ «مُدٌّ مِنْ طَعَامٍ فِي كُلِّ يَوْمٍ ».
Hadith.1793 - Iys ibn al-Qasim asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq 
) about someone who does not fast the three days of every month and finds fasting difficult. Is there a compensation for this?
Imam said: "A mudd (a measure) of food for each day."
