٢١ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ عَلِيِّ بْنِ الْحَسَنِ بْنِ رِبَاطٍ عَنْ بَعْضِ رِجَالِهِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ لا يَزَالُ الْعَبْدُ الْمُؤْمِنُ يُكْتَبُ مُحْسِناً مَا دَامَ سَاكِتاً فَإِذَا تَكَلَّمَ كُتِبَ مُحْسِناً أَوْ مُسِيئاً. 
21. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Ali ibn al-Hassan ibn Ribat from certain individuals of his people from Abu ‘Abdillah  who has said the following: “A believing servant (of Allah) is considered a person of good deeds as long as he does not speak. When he speaks he is considered a person of good deeds or of evil deeds.”
