Riyad as-Salihin, Book 1, Hadith 447 (In-Book) ⓘ
Anas bin Malik (May Allah be pleased with him) reported: Messenger of Allah delivered a Khutbah to us the like of which I had never heard from him before. In the course of the Khutbah, he said: "If you knew what I know, you would laugh little and weep much". Thereupon those present covered their faces and began to sob.[Al- Bukhari and Muslim].
وعن أنس، رضي الله عنه ، قال: خطب رسول الله، صلى الله عليه وسلم، خطبة ما سمعت مثلها قط، فقال: "لو تعلمون ما أعلم لضحكتم قليلاً ولبكيتم كثيراً" قال : فغطي أصحاب رسول الله صلى الله عليه وسلم وجوههم، ولهم خنين ، ((متفق عليه)) ، وسبق بيان في باب الخوف.
