عَنْ جَابِرِ بْنِ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا صَلَّى الْغَدَاةَ جَلَسَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ حَسَنَاءَ أَوْ تَرْتَفِعَ الشَّمْسُ حَسَنَاءَ
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) performed the Fajr prayer, he would remain seated on his prayer mat until the sun had risen well or had become high.
