٨- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ سَهْلٍ عَنْ زَكَرِيَّا بْنِ آدَمَ قَالَ سَأَلْتُ الرِّضَا (عَلَيْهِ السَّلام) عَنْ قَوْمٍ مِنَ الْعَدُوِّ صَالَحُوا ثُمَّ خَفَرُوا وَلَعَلَّهُمْ إِنَّمَا خَفَرُوا لأنَّهُ لَمْ يُعْدَلْ عَلَيْهِمْ أَيَصْلُحُ أَنْ يُشْتَرَى مِنْ سَبْيِهِمْ فَقَالَ إِنْ كَانَ مِنْ عَدُوٍّ قَدِ اسْتَبَانَ عَدَاوَتُهُمْ فَاشْتَرِ مِنْهُمْ وَإِنْ كَانَ قَدْ نَفَرُوا وَظَلَمُوا فَلا تَبْتَعْ مِنْ سَبْيِهِمْ قَالَ وَسَأَلْتُهُ عَنْ سَبْيِ الدَّيْلَمِ يَسْرِقُ بَعْضُهُمْ مِنْ بَعْضٍ وَيُغِيرُ الْمُسْلِمُونَ عَلَيْهِمْ بِلا إِمَامٍ أَيَحِلُّ شِرَاؤُهُمْ قَالَ إِذَا أَقَرُّوا بِالْعُبُودِيَّةِ فَلا بَأْسَ بِشِرَائِهِمْ قَالَ وَسَأَلْتُهُ عَنْ قَوْمٍ مِنْ أَهْلِ الذِّمَّةِ أَصَابَهُمْ جُوعٌ فَأَتَاهُ رَجُلٌ بِوَلَدِهِ فَقَالَ هَذَا لَكَ فَأَطْعِمْهُ وَهُوَ لَكَ عَبْدٌ فَقَالَ لا تَبْتَعْ حُرّاً فَإِنَّهُ لا يَصْلُحُ لَكَ وَلا مِنْ أَهْلِ الذِّمَّةِ.
8. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn Sahl from Zakariya ibn Adam who has said the following: “I once asked al-Rida’ , about the enemy people who make peace, then breach it because justice was not practiced with them; if it is permissible to buy their captives. He (the Imam) said, ‘If they are open enemies you can buy but if they are exiled and treated unjustly, then do not buy their captives.’ I asked him (the Imam) about captives from Daylam who steal from each other and the Muslims invade them without authorization from Imam; if buying them is permissible. He (the Imam) said, ‘If they confess their slavery, then it is not unlawful.’ I then asked him (the Imam) about taxpayer people who face famine and a man brings his children and says: this is for you feed him and he is for you. He (the Imam) said, ‘You must not sell free people. It is not lawful for you as well as for the tax payers.’”
