5- حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ مُحَمَّدِ بْنِ سَمَاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ اللهِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ عَلَيْهِ كُرٌّ مِنْ طَعَامٍ فَاشْتَرَى كُرّاً مِنْ رَجُلٍ آخَرَ فَقَالَ لِلرَّجُلِ انْطَلِقْ فَاسْتَوْفِ كُرَّكَ قَالَ لا بَأْسَ بِهِ.

5. Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad ibn Sama‘ah from more than one person from Aban ibn ‘Uthman from ‘Abd al-Rahman ibn abu ‘Abd Allah who has said the following: “This is concerning my question before abu ‘Abd Allah, ‘Alayhi al-Salam, about the case of a man who owes one kur (a certain amount) of food. He then buys one kur of food from another man and asks his creditor to come to receive the Kur of food owed to him. He (the Imam) said, ‘Such a transaction is not harmful.’”
