426 — Muhammad ibn Idris narrated to me: Abu al-Nadr al-Dimashqī narrated to us: Ismā'īl ibn Ayyāsh narrated to us, from Abu Salama al-San'ānī, from Ka'b, who said:

“Speaking little is profound wisdom. You should therefore observe silence, for it is an excellent form of restraint, entails little burden, and leaves one less encumbered by sins.”
