٧- أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ سَيْفٍ التَّمَّارِ قَالَ قُلْتُ لأبِي بَصِيرٍ أُحِبُّ أَنْ تَسْأَلَ أَبَا عَبْدِ اللهِ (عَلَيْهِ السَّلام) عَنْ رَجُلٍ اسْتَبْدَلَ قَوْصَرَتَيْنِ فِيهِمَا بُسْرٌ مَطْبُوخٌ بِقَوْصَرَةٍ فِيهَا تَمْرٌ مُشَقَّقٌ قَالَ فَسَأَلَهُ أَبُو بَصِيرٍ عَنْ ذَلِكَ فَقَالَ (عَلَيْهِ السَّلام) هَذَا مَكْرُوهٌ فَقَالَ أَبُو بَصِيرٍ وَلِمَ يُكْرَهُ فَقَالَ كَانَ عَلِيُّ بْنُ أَبِي طَالِبٍ (عَلَيْهِ السَّلام) يَكْرَهُ أَنْ يَسْتَبْدِلَ وَسْقاً مِنْ تَمْرِ الْمَدِينَةِ بِوَسْقَيْنِ مِنْ تَمْرِ خَيْبَرَ لأنَّ تَمْرَ الْمَدِينَةِ أَدْوَنُهُمَا وَلَمْ يَكُنْ عَلِيٌّ (عَلَيْهِ السَّلام) يَكْرَهُ الْحَلالَ.
7. Ahmad ibn Muhammad has narrated from al-Hassan ibn Mahbub from Sayf al-Tammar who has said the following: “I once asked abu Basir to ask abu ‘ Abd Allah , about the case of a man who exchanges two baskets of fresh half-ripe dates for one basket of Mushaqaq (stone-free) dates. Abu Basir asked him (the Imam) and he (the Imam) said, ‘It is Makruh (detestable).’ Abu Basir then asked, ‘Why it is Makruh (detestable)?’ He (the Imam) said, ‘Ali ibn abu Talib , disliked to exchange one wasaq of dates of al-Madinah for two wasaq (a certain unit of measurement) of dates of Khaybar because dates of al-Madinah are of inferior quality and Ali , would not dislike lawful things.’”
