The Time That The Prophet (saws) Would Pray At Night
Sunan Abi Dawud
حَدَّثَنَا أَبُو تَوْبَةَ، عَنْ إِبْرَاهِيمَ بْنِ سَعْدٍ، عَنْ أَبِيهِ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، قَالَتْ : مَا أَلْفَاهُ السَّحَرُ عِنْدِي إِلاَّ نَائِمًا، تَعْنِي النَّبِيَّ صلى الله عليه وسلم .
Narrated 'Aishah: When he was with me he would sleep at dawn. By this she referred to the Prophet (ﷺ).
