KNOWLEDGE OF THE PROPHET, praise and peace be upon H him, H 448 "The Prophet, praise and peace be upon him, gave a sermon, the like of which I (Anas) had never heard from him before. During it he said: 'If you knew what I know, you would laugh a little and weep a lot.' Anas added 'The Companions of the Prophet covered their heads while they wept.'" R 448 Bukhari and Muslim with a chain up to Anas who related this hadith
447- وعن أنس رضي الله عنه ، قَالَ : خطب رسول الله صلى الله عليه وآله وسلم خُطْبَةً مَا سَمِعْتُ مِثْلَهَا قَطُّ ، فقال : "لَوْ تَعْلَمُونَ مَا أعْلَمُ ، لَضَحِكْتُمْ قَليلاً وَلَبَكَيْتُمْ كَثِيراً" قَالَ : فَغَطَّى أصْحَابُ رسول الله صلى الله عليه وآله وسلم وُجُوهَهُمْ ، وَلَهُمْ خَنِينٌ . متفقٌ عَلَيْهِ . وَسَبقَ بَيَانُهُ في بَابِ الخَوْفِ .
