The Messenger of Allah ﷺ said, "By Him in whose hand is Muhammad's soul, if you knew what I know, you would laugh little and weep much."
وقال رسول الله ﷺ والذي نفس محمد بيده لو تعلمون ما أعلم لضحكتم قليلا ولبكيتم كثيرا
This hadith is also sahih, and it is found in the individual Sahifah, numbered 14, where the two following hadiths, 8111 and 8112, precede it, and the hadith following this one, 8110, has been omitted from it. Bukhari narrated it [8:130 print / 11:459 Fath] through the route of the Sahifah, but not through the narration of Abdul-Razzaq. He narrated it from Ibrahim bin Musa, from Hisham bin Yusuf, from Mamar, from Hammam bin Munabbih, and it has already occurred in the Musnad at 7490 from the copy of Araj as well. Bukhari also narrated it at 11:273 Fath, along with the narration of Saeed bin Musayab from Abu Hurairah. In the narration of the individual Sahifah, weeping is mentioned before laughing, which agrees with Bukhari's narration through the route of Hammam, whereas what we have established here is what is fixed in the original manuscripts of the Musnad and in Jami al-Masanid, and this agrees with Bukhari's narration through the route of Saeed.
