١- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ إِبْرَاهِيمَ الْكَرْخِيِّ قَالَ اشْتَرَيْتُ لأبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) جَارِيَةً فَلَمَّا ذَهَبْتُ أَنْقُدُهُمُ الدَّرَاهِمَ قُلْتُ أَسْتَحِطُّهُمْ قَالَ لا إِنَّ رَسُولَ اللهِ (صَلَّى اللهُ عَلَيْهِ وَآلِه) نَهَى عَنِ الاسْتِحْطَاطِ بَعْدَ الصَّفْقَةِ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Ibrahim al-Kharkhiy who has said the following: “I once bought a slave-girl for abu ‘ Abd Allah , and went to get dirhams and I asked him (the Imam), ‘Can I ask to reduce the price ? 5 He (the Imam) said, ‘No, because the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, prohibited asking for reduction after the deal is finalized.’”
