حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي مِنَ اللَّيْلِ إِحْدَى عَشْرَةَ رَكْعَةً، فَإِذَا طَلَعَ الْفَجْرُ صَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ، ثُمَّ اضْطَجَعَ عَلَى شِقِّهِ الأَيْمَنِ، حَتَّى يَجِيءَ الْمُؤَذِّنُ فَيُؤْذِنَهُ.
