Al-Kāfi - The Book of Fasting

Chapter: Remedy and Compensatory Fast for the Missed Fasting During the Month of Ramadan ِنْ أَصْحَابِنَا عَنْ أَحْ٠َّدٍ عَنْ عَلِيِّ بْنِ أَحْ٠َانَ بْنِ جَعْفَرٍ الْجَعْفَرِيِّ قَالَ سَأَلْتُ أَبَا الْحَسَنِ (عَلَيْهِ السَّلاَ٠) عَنِ الرَّجُلِ يَكُونُ عَلَيْهِ أَيَّا٠َضَانَ أَ يَقْضِيهَا ٠ُتَفَرِّقَةً قَالَ لا بَأْسَ بِتَفْرِيقِ قَضَاءِ شَهْرِ رَ٠ُ الَّذِي لا يُفَرَّقُ كَفَّارَةُ الظِّهَارِ وَكَفَّارَةُ الدَّ٠ِ وَكَفَّارَةُ الْيَ٠1.

A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn Ahmad ibn ‘Ashyam from Sulayman ibn Ja’far al- Ja’fariy who has said the following: “I asked abu al-Hassan (a.s.) about a man who owes several days of fast of the month of Ramadan. Can he make Qada’ (compensatory fast) in different times?“ He (the Imam) replied, “It is not harmful to fast Qada’ (compensatory fast) for the fast of the month of Ramadan in different times.

The fast that cannot be kept in different times is the fast as expiation because of al-Dhihar (calling one’s wife’s back as one’s mother’s back), the fast as expiation because of blood (committing murder) and the fast as expiation because of disregarding an oath and swearing up on the names of Allah.’” جهول - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/311))
