٣- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ الْعَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ السَّلام) قَالَ إِذَا سَمِعَ الرَّجُلُ الشَّهَادَةَ وَلَمْ يُشْهَدْ عَلَيْهَا فَهُوَ بِالْخِيَارِ إِنْ شَاءَ شَهِدَ وَإِنْ شَاءَ سَكَتَ إِلا إِذَا عَلِمَ مِنَ الظَّالِمِ فَلْيَشْهَدْ وَلا يَحِلُّ لَهُ إِلا أَنْ يَشْهَدَ.
