وَ سَأَلَ سُلَيْمَانُ بْنُ جَعْفَرٍ اَلْجَعْفَرِيُّ أَبَا اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلرَّجُلِ يَكُونُ عَلَيْهِ أَيَّامٌ مِنْ شَهْرِ رَمَضَانَ أَ يَقْضِيهَا مُتَفَرِّقَةً قَالَ «لاَ بَأْسَ بِتَفْرِقَةِ قَضَاءِ شَهْرِ رَمَضَانَ إِنَّمَا اَلصِّيَامُ اَلَّذِي لاَ يُفَرَّقُ صَوْمُ كَفَّارَةِ اَلظِّهَارِ وَ كَفَّارَةِ اَلدَّمِ وَ كَفَّارَةِ اَلْيَمِينِ ».
Sulaiman ibn Ja'far Al-Ja'fari asked Abu Al-Hasan Al-Ridha (a.s) about a man who has missed days from the Month of Ramadan. Can he make them up non-consecutively? Imam (a.s) replied: "There is no harm in making up the fasts of the Month of Ramadan separately. The fasting that must not be separated is the fast of expiation for zhihar, expiation for shedding blood, and expiation for breaking an oath."
