1- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ زِيَادٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) إِيَّاكُمْ وَنِكَاحَ الزِّنْجِ فَإِنَّهُ خَلْقٌ مُشَوَّهٌ.
1. Ali b. Ibrahim from Harun b. Muslim from Mas’adah b. Ziyad ¹ from Abu Abdillah (as) who said that Amir al-Mu’mineen (as) said: ’Be aware of marrying the people of al-Zanj, for they are a distorted creature.'
