وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، قَالَ أَبُو بَكْرٍ وَحَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، عَنْ زَكَرِيَّاءَ، كِلاَهُمَا عَنْ سِمَاكٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا صَلَّى الْفَجْرَ جَلَسَ فِي مُصَلاَّهُ حَتَّى تَطْلُعَ الشَّمْسُ حَسَنًا .
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.
