Al-Kāfi - Volume 6 > Undesirability of Making the Guest Work
Hadith #3

مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُوسَى عَنْ ذُبْيَانَ بْنِ حَكِيمٍ عَنْ مُوسَى بْنِ أُكَيْلٍ النُّمَيْرِيِّ عَنْ مَيْسَرَةَ قَالَ قَالَ أَبُو جَعْفَرٍ ( عليه السلام ) إِنَّ مِنَ التَّضْعِيفِ تَرْكَ الْمُكَافَأَةِ وَ مِنَ الْجَفَاءِ اسْتِخْدَامَ الضَّيْفِ فَإِذَا نَزَلَ بِكُمُ الضَّيْفُ فَأَعِينُوهُ وَ إِذَا ارْتَحَلَ فَلَا تُعِينُوهُ فَإِنَّهُ مِنَ النَّذَالَةِ وَ زَوِّدُوهُ وَ طَيِّبُوا زَادَهُ فَإِنَّهُ مِنَ السَّخَاءِ .

3. Muhammad ibn Yahya has narrated from Ahmad ibn Musa from Dhubyan ibn Hakim from Musa ibn ’Ukayl al-Numayriy from May sarah who has said the following: “Abu Ja‘far, ‘Alayhi al-Salam, has said, ‘Ignoring to counter-balance a favor that one receives is one of the reasons to weaken one; and it is of injustice to make a guest to work. When a guest comes to you help him. When he leaves do not help him to leave, it is of lowliness. You must provide him supplies and make his supplies good; it is an act of generosity.’”
