"I said to Jabir bin Samurah: 'Did you used to sit with the Messenger of Allah ﷺ?" He said: 'Yes.' When the Messenger of Allah ﷺ had prayed fajr, he would sit in the place where he had prayed until the sun rose, and his companions would talk and remember things from the time of Jahilliyah and recite poetry, and they would laugh and he would smile.'" (Using translation from Nasāʾī 1358)  

قُلْتُ لِجَابِرِ بْنِ سَمُرَةَ كُنْتَ تُجَالِسُ رَسُولَ اللهِ ﷺ؟ قَالَ «نَعَمْ كَانَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى الْفَجْرَ جَلَسَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ فَيَتَحَدَّثُ أَصْحَابُهُ وَيَذْكُرُونَ حَدِيثَ الْجَاهِلِيَّةِ وَيُنْشِدُونَ الشِّعْرَ وَيَضْحَكُونَ وَيَتَبَسَّمُ»
