Simak narrated on the authority of Jabir b. Samura that when the Messenger of Allah ﷺ observed the dawn prayer, he sat at the place of worship till the sun had risen enough.  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا صَلَّى الْفَجْرَ جَلَسَ فِي مُصَلاَّهُ حَتَّى تَطْلُعَ الشَّمْسُ حَسَنًا  

"When the Messenger of Allah ﷺ prayed fajr, he would sit in the place where he had prayed until the sun rose." (Using translation from Nasāʾī 1357)   

كَانَ رَسُولُ اللهِ ﷺ إِذَا صَلَّى الْغَدَاةَ جَلَسَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ حَسْنَاءَ  

"When the Prophet prayed Fajr he would remain seated where he had prayed until the sun had risen." (Using translation from Tirmidhī 585)   

كَانَ النَّبِيُّ ﷺ إِذَا صَلَّى الْفَجْرَ جَلَسَ فِي مُصَلَّاهُ لَمْ يَرْجِعْ حَتَّى تَطْلُعَ الشَّمْسُ  

[Machine] The Prophet ﷺ used to sit in his mosque from the time the dawn broke until the sun rose beautifully.  

كَانَ النَّبِيُّ ﷺ «يَجْلِسُ فِي مُصَلَّاهُ إِذَا طَلَعَ الْفَجْرُ حَتَّى تَطْلُعَ الشَّمْسُ حَسْنَاءَ»  

"When the Prophet prayed Fajr he would remain seated where he had prayed until the sun had risen." (Using translation from Tirmidhī 585)  

«كَانَ النَّبِيُّ ﷺ إِذَا صَلَّى الْفَجْرَ قَعَدَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ»  

"When the Prophet prayed Fajr he would remain seated where he had prayed until the sun had risen." (Using translation from Tirmidhī 585)  

«أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا صَلَّى الْفَجْرَ قَعَدَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ»  

"كَانَ النَّبِىُّ ﷺ إِذَا صَلَّى الْغَدَاةَ قَعَدَ في مَجْلِسِهِ حَتَّى تَطْلُعَ الشَّمْسُ".
