The Sufficient (Vol 7) · Hadith 854 (#Ḥadīth #10)

10- أَبُو عَلِيٍّ الأشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ قَالَ كَتَبَ بُنْدَارُ مَوْلَى إِدْرِيسَ يَا سَيِّدِي نَذَرْتُ أَنْ أَصُومَ كُلَّ يَوْمِ سَبْتٍ فَإِنْ أَنَا لَمْ أَصُمْهُ مَا يَلْزَمُنِي مِنَ الْكَفَّارَةِ فَكَتَبَ وَقَرَأْتُهُ لا تَتْرُكْهُ إِلا مِنْ عِلَّةٍ وَلَيْسَ عَلَيْكَ صَوْمُهُ فِي سَفَرٍ وَلا مَرَضٍ إِلا أَنْ تَكُونَ نَوَيْتَ ذَلِكَ وَإِنْ كُنْتَ أَفْطَرْتَ مِنْهُ مِنْ غَيْرِ عِلَّةٍ فَتَصَدَّقْ بِعَدَدِ كُلِّ يَوْمٍ لِسَبْعَةِ مَسَاكِينَ نَسْأَلُ اللهَ التَّوْفِيقَ لِمَا يُحِبُّ وَيَرْضَى.

10. Abu Ali al-Ash‘ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Ali ibn Mahziyar from who has narrated the following: “Bundar, maxvla of Idris, once wrote, ‘My master, I made a vow and commitment to fast every Saturday; and if I did not fast what is the expiation?’ He (the Imam) wrote and I read it, ‘Do not stop fasting except because of illness, and you do not have to fast when on a journey or during your illness unless you had the intention to do so. If you stop fasting without illness and good reason, then pay charity for every day missed to seven destitute people, we ask Allah to grant good opportunity for doing what He loves and pleases.’”
