The Prophet (ﷺ), when he performed the Fajr prayer, would remain seated in his prayer place until the sun rose brightly

It was from the Sunnah of the Prophet (ﷺ) that when he performed the Fajr prayer, he would remain seated in his prayer place until the sun rose high. He would not leave his place of prayer where he had performed Fajr until the sun had risen. When the sun had risen, he would stand up, and they would begin talking, mentioning some matters from their pre-Islamic days while he remained silent. They would laugh, and he would sometimes smile with them.
