28. hadíth
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 ».
Iys ibn al-Qasim asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq (a.s)) about someone who does not fast the three days of every month and finds fasting difficult. Is there a compensation for this? Imam (a.s) said: "A mudd (a measure) of food for each day."
