Chapter 56 | Silence and Controlling the Tongue
6ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ الأشْعَرِيِّ عَنِ ابْنِ الْقَدَّاحِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ لُقْمَانُ لإبْنِهِ يَا بُنَيَّ إِنْ كُنْتَ زَعَمْتَ أَنَّ الْكَلامَ مِنْ فِضَّةٍ فَإِنَّ السُّكُوتَ مِنْ ذَهَبٍ.
6. A number of our people have narrated from Sahl ibn Ziyad from Ja’far ibn Muhammad al- Ash’ari from ibn al-Qaddah from Abu ‘Abdillah who has said the following: “Luqman (who is mentioned in Chapter 3 1 of the Holy Quran) said to his son, ‘My son, if you think speaking is silver, note it down that silence is gold.’”
