It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that he said: "Adopting silence is pure wisdom, but those who act upon it are very few."
Imam Abu Ya'la narrated this hadith in his Musnad. The narrator in its chain, Uthman bin Sa'd al-Katib, is da'if (weak); therefore this narration is weak in its chain, although its meaning is established by other authentic hadith and reports.
