Al-Kāfi|Volume 4|Book 2|Chapter 65
3ـ عَلِيُّ بْنُ مُحَمَّدِ بْنِ بُنْدَارَ وَغَيْرُهُ عَنْ إِبْرَاهِيمَ بْنِ إِسْحَاقَ بِإِسْنَادٍ ذَكَرَهُ عَنِ الْفُضَيْلِ بْنِ يَسَارٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلاَم) قَالَ قَالَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) إِذَا دَخَلَ رَجُلٌ بَلْدَةً فَهُوَ ضَيْفٌ عَلَى مَنْ بِهَا مِنْ أَهْلِ دِينِهِ حَتَّى يَرْحَلَ عَنْهُمْ وَلا يَنْبَغِي لِلضَّيْفِ أَنْ يَصُومَ إِلاَّ بِإِذْنِهِمْ لِئَلاَّ يَعْمَلُوا الشَّيْءَ فَيَفْسُدَ عَلَيْهِمْ وَلا يَنْبَغِي لَهُمْ أَنْ يَصُومُوا إِلاَّ بِإِذْنِ الضَّيْفِ لِئَلاَّ يَحْتَشِمَهُمْ فَيَشْتَهِيَ الطَّعَامَ فَيَتْرُكَهُ لَهُمْ.
3. Ali ibn Muhammad ibn Bandar [and others] from Ibrahim ibn Ishaq through his chain of narrators from al-Fadl ibn Yasar who has said the following: “Abu Ja‘far عليه السلام, has stated this Hadith: ‘The Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, “When a man enters a town (residence), he is a guest of the inhabitants of that town who are followers of the religion he follows until he leaves that town (residence). It is not proper for him to fast without their permission, so that the food that may have been prepared does not spoil. It is not proper for them also to fast without permission so he because of exercising reservation does not eat the food that he desires.’””
