4ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي إِبْرَاهِيمَ (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ جَعَلَ عَلَى نَفْسِهِ صَوْمَ شَهْرٍ بِالْكُوفَةِ وَشَهْرٍ بِالْمَدِينَةِ وَشَهْرٍ بِمَكَّةَ مِنْ بَلاءٍ ابْتُلِيَ بِهِ فَقُضِيَ أَنَّهُ صَامَ بِالْكُوفَةِ شَهْراً وَدَخَلَ الْمَدِينَةَ فَصَامَ بِهَا ثَمَانِيَةَ عَشَرَ يَوْماً وَلَمْ يُقِمْ عَلَيْهِ الْجَمَّالُ قَالَ يَصُومُ مَا بَقِيَ عَلَيْهِ إِذَا انْتَهَى إِلَى بَلَدِهِ.
4. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah who has said the following: “I once asked abu Ibrahim (a.s.), about a man who has made obligatory upon himself to fast one month in al-Kufah, one month in al-Madinah and one month in Makkah because of an affliction whereby he suffered. He fasted one month in al-Kufah, then he entered al-Madinah and fasted for eighteen days, but then the camel man did not stay any longer. He (the Imam) said, ‘He can fast the remaining days at home when he comes back.’”
