Chapter 56 | The Case of One Who Owes Fasting of Two Consecutive Months but an Obstacle Prevents Him
5ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ مَنْصُورِ بْنِ حَازِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) أَنَّهُ قَالَ فِي رَجُلٍ صَامَ فِي ظِهَارٍ شَعْبَانَ ثُمَّ أَدْرَكَهُ شَهْرُ رَمَضَانَ قَالَ يَصُومُ رَمَضَانَ وَيَسْتَأْنِفُ الصَّوْمَ فَإِنْ هُوَ صَامَ فِي الظِّهَارِ فَزَادَ فِي النِّصْفِ يَوْماً قَضَى بَقِيَّتَهُ.
5. Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya from Mansur who has said the following: “About a man who fasts because of Zihar in the month of al-Sha‘ban, then the month of Ramadan comes; abu ‘Abd Allah , has said, ‘He is required to fast the month of Ramadan, then resume the fast. If because of Zihar he fasted for more than half by one day he completes only Qada’ (compensatory fast) of the rest.’”
