سَأَلْتُ أَبَا عَبْدِ اللَّهِ ع عَنِ الَّذِي يُرَدُّ مِنَ الشُّهُودِ فَقَالَ الظَّنِينُ وَ الْخَصْمُ قَالَ قُلْتُ فَالْفَاسِقُ وَ الْخَائِنُ قَالَ فَقَالَ كُلُّ هَذَا يَدْخُلُ فِي الظَّنِينِ[2].
“I once asked abu ‘Abd Allah (a.s.), about the witnesses whose testimony is rejected. He (the Imam) said, ‘Of such people are a pessimist and an antagonist.’ I then asked, ‘What about a sinful and a treacherous one?’ He (the Imam) said, ‘Such ones are included in “pessimist”.”’
