7- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) أَنَّ أَمِيرَ الْمُؤْمِنِينَ (صَلَّى اللهُ عَلَيْهِ وَآلِه) كَانَ لا يَقْبَلُ شَهَادَةَ فَحَّاشٍ وَلا ذِي مُخْزِيَةٍ فِي الدِّينِ.
7. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy from al-Sakuniy who has narrated the following: “Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin, Ali (a.s.), would not accept the testimony of persons of offensive manners and those humiliated by law.”
