2- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي نَجْرَانَ عَنْ عَاصِمِ بْنِ حُمَيْدٍ عَنْ مُحَمَّدِ بْنِ قَيْسٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) فِي رَجُلٍ أَعْطَى رَجُلا وَرِقاً فِي وَصِيفٍ إِلَى أَجَلٍ مُسَمًّى فَقَالَ لَهُ صَاحِبُهُ لا نَجِدُ لَكَ وَصِيفاً خُذْ مِنِّي قِيمَةَ وَصِيفِكَ الْيَوْمَ وَرِقاً قَالَ فَقَالَ لا يَأْخُذُ إِلا وَصِيفَهُ أَوْ وَرِقَهُ الَّذِي أَعْطَاهُ أَوَّلَ مَرَّةٍ لا يَزْدَادُ عَلَيْهِ شَيْئاً.

2. Ali ibn Ibrahim has narrated from his father from ‘Abd al-Rahman ibn abu Najran from ‘Asim ibn Hamid from Muhammad ibn Qays who has said the following: “Abu Ja‘far, ‘Alayhi al-Salam, has said that ’Amir al-Mu’minin, about the case of a man who gave a note to another man for a servant for an appointed time and his party said, ‘I could not find a servant for you, you take from me the cost of your servant today in the form of the value.’ He (’Amir al- Mu’minin) has said, ‘He can refuse to take anything other than his servant or the note that he had given him at first without any thing added.’”
