رُوِيَ عَنْ عُبَيْدِ اَللَّهِ بْنِ عَلِيٍّ اَلْحَلَبِيِّ قَالَ: سُئِلَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَمَّا يُرَدُّ مِنَ اَلشُّهُودِ فَقَالَ "اَلظَّنِينُ وَ اَلْمُتَّهَمُ وَ اَلْخَصْمُ" قَالَ قُلْتُ فَالْفَاسِقُ وَ اَلْخَائِنُ قَالَ "هَذَا يَدْخُلُ فِي اَلظَّنِينِ".
It is narrated from Ubaydullah ibn Ali Al-Halabi, who said: Abu Abdullah (a.s) was asked about the categories of witnesses whose testimony is to be rejected. Imam (a.s) replied: "The one suspected (Al-Zaneen), the accused (Al-Muttaham), and the adversary (Al-Khasm)." I said: "What about the immoral (Al-Fasiq) and the dishonest (Al-Kha'in)?" Imam (a.s) said: "These fall under the category of the suspected (Al-Zaneen)."
