3- 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.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has narrated the following: “Abu Ja’far (a.s.), has said, ‘If a man hears a testimony but has not witnessed it, he has the choice to testify or remain silent, unless he knows that a rightful party suffers injustice, in which case it is not lawful to remain silent.’”
