صحيح مسلم

Simak b. Harb reported: I said to Jabir b. Samura: Did you have the privilege of sitting in the company of Allah's Messenger (ﷺ)? He said: Yes, very frequently, and added: He did not stand up (and go) from the place where he offered the dawn prayer until the sun rose, and after the rising of the sun he stood up, and they (his Companions) entered into conversation with one another and they talked of the things (that they did during the Days of Ignorance), and they laughed (on their unreasonable and ridiculous acts). Allah's Messenger (ﷺ) smiled only.
