فِي رَجُلٍ جَعَلَ عَلَيْهِ صَوْمَ شَهْرٍ فَصَامَ مِنْهُ خَمْسَةَ عَشَرَ يَوْماً ثُمَّ عَرَضَ لَهُ أَمْرٌ فَقَالَ إِنْ كَانَ صَامَ خَمْسَةَ عَشَرَ يَوْماً فَلَهُ أَنْ يَقْضِيَ مَا بَقِيَ وَ إِنْ كَانَ أَقَلَّ مِنْ خَمْسَةَ عَشَرَ يَوْماً لَمْ يُجْزِئْهُ حَتَّى يَصُومَ شَهْراً تَامّاً .
Translation
A number of our companions, from Ahmad Bin Muhammad, from Ali Bin Al Hakam, from Musa Bin Bakr, from Al Fuzayl, (It has been narrated) from Abu Abdullah<sup>asws</sup> having said regarding a man upon whom were Fasts of a month, so he Fasts fifteen days, then a matter presents itself, said: ‘If he had Fasted fifteen days, so for him it that he makes up for what remains, and even if it was less than fifteen days, it would not suffice for him until he Fasts a month completely’.
