Sahih Muslim , Book 5, Hadith 361 (In-Book) ⓘ

Simak b. Harb reported: I said to Jabir b. Samura: Did you sit in the company of the Messenger of Allah (may peace he upon him)? He said: Yes, very often. He (the Holy Prophet) used to sit at the place where he observed the morning or dawn prayer till the sun rose or when it had risen; he would stand, and they (his Companions) would talk about matters (pertaining to the days) of ignorance, and they would laugh (on these matters) while (the Holy Prophet) only smiled.

حَدَّثَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا سِمَاكٌ، ح وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، - وَاللَّفْظُ لَهُ - قَالَ أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، قَالَ قُلْتُ لِجَابِرِ بْنِ سَمُرَةَ أَكُنْتَ تُجَالِسُ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ نَعَمْ كَثِيرًا كَانَ لاَ يَقُومُ مِنْ مُصَلاَّهُ الَّذِي يُصَلِّي فِيهِ الصُّبْحَ أَوِ الْغَدَاةَ حَتَّى تَطْلُعَ الشَّمْسُ فَإِذَا طَلَعَتِ الشَّمْسُ قَامَ وَكَانُوا يَتَحَدَّثُونَ فَيَأْخُذُونَ فِي أَمْرِ الْجَاهِلِيَّةِ فَيَضْحَكُونَ وَيَتَبَسَّمُ ‏.‏
