وَ رَوَى عَلِيُّ بْنُ أَسْبَاطٍ عَنْ مُحَمَّدِ بْنِ اَلصَّلْتِ قَالَ: سَأَلْتُ أَبَا اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ عَنْ رِفْقَةٍ كَانُوا فِي طَرِيقٍ فَقُطِعَ عَلَيْهِمُ اَلطَّرِيقُ فَأُخِذَ اَللُّصُوصُ فَشَهِدَ بَعْضُهُمْ لِبَعْضٍ فَقَالَ "لاَ تُقْبَلُ شَهَادَتُهُمْ إِلاَّ بِالْإِقْرَارِ مِنَ اَللُّصُوصِ أَوْ شَهَادَةٍ مِنْ غَيْرِهِمْ عَلَيْهِمْ ".
And Ali ibn Asbat narrated from Muhammad ibn Al-Salt who said: I asked Abu Al-Hasan Al-Ridha (a.s) about a group of travelers who were ambushed by robbers on their journey. The robbers were captured, and some of them testified in favor of the others. Imam (a.s) replied: "Their testimony is not accepted except if it is accompanied by a confession from the robbers themselves or testimony against them from others."
