Hadith 16:42
Anas (RAA) narrated that Allah's Messenger (ﷺ) said:
“Keeping silent is considered as (an act of`) wisdom, but very few practice it.” Related by Al-Baihaqi in his book Shu'ab al-Iman with a weak chain of narrators a he deemed the sound view is that it is traced back to one of the companions who quoted it from Luqman Al-Hakim.
وَعَنْ أَنَسٍ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ اَلصَّمْتُ حِكْمَةٌ, وَقَلِيلٌ فَاعِلُهُ } أَخْرَجَهُ اَلْبَيْهَقِيُّ فِي " اَلشُّعَبِ" بِسَنَدٍ ضَعِيفٍ وَصَحَّحَ أَنَّهُ مَوْقُوفٌ مِنْ قَوْلِ لُقْمَانَ اَلْحَكِيمِ
