Hadith 4865
وَعَن عِمْرَانَ بْنِ حُصَيْنٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَقَامُ الرَّجُلِ بِالصَّمْتِ أَفْضَلُ مِنْ عِبَادَةِ سِتِّينَ سنة»
It is narrated from Imran bin Husain (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "A man's maintaining silence (from saying bad things) is better than sixty years of worship." Its chain is weak; it was narrated by Al-Bayhaqi in Shu'ab al-Iman.
