5- مُحَمَّدٌ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ النَّضْرِ بْنِ سُوَيْدٍ عَنِ ابْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَنَّهُ قَالَ فِي الرَّجُلِ يَشْتَرِي الْغُلامَ أَوِ الْجَارِيَةَ وَلَهُ أَخٌ أَوْ أُخْتٌ أَوْ أَبٌ أَوْ أُمٌّ بِمِصْرٍ مِنَ الأمْصَارِ قَالَ لا يُخْرِجْهُ إِلَى مِصْرٍ آخَرَ إِنْ كَانَ صَغِيراً وَلا يَشْتَرِهِ فَإِنْ كَانَتْ لَهُ أُمٌّ فَطَابَتْ نَفْسُهَا وَنَفْسُهُ فَاشْتَرِهِ إِنْ شِئْتَ.
5. Muhammad has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from ibn Sinan from abu 'Abdillah (AS) who said: “Regarding a man who buys a slave-girl or a slave boy who has a brother or sister, or a father or mother in a city of the cities, he must not take such slave out of that city to another city if the slave is a minor, and must not buy such slaves but if the slave has a mother who agrees as well as the slave, then you can buy.”
