Lying Down On One's Side After It
Sunan Abi Dawud
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ زِيَادِ بْنِ سَعْدٍ، عَمَّنْ حَدَّثَهُ - ابْنِ أَبِي عَتَّابٍ، أَوْ غَيْرِهِ - عَنْ أَبِي سَلَمَةَ، قَالَ قَالَتْ عَائِشَةُ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا صَلَّى رَكْعَتَىِ الْفَجْرِ فَإِنْ كُنْتُ نَائِمَةً اضْطَجَعَ وَإِنْ كُنْتُ مُسْتَيْقِظَةً حَدَّثَنِي .
Narrated Aisha, Ummul Mu'minin: When the Prophet (ﷺ) prayed the two rak'ahs of the dawn prayer, he would lie down if I was asleep; in case I was awake, he would talk to me.
