(476) بَابُ الرُّخْصَةِ فِي تَرْكِ الِاضْطِجَاعِ بَعْدَ رَكْعَتَيِ الْفَجْرِ،
The chapter on the concession to skip lying down after the two units before Fajr
Hadith 1122
نَا سَعِيدُ بْنُ عَبْدِ الرَّحْمَنِ الْمَخْزُومِيُّ ، حَدَّثَنَا سُفْيَانُ ، عَنْ سَالِمٍ أَبِي النَّضْرِ ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ ، عَنْ عَائِشَةَ ، قَالَتْ : " كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّي رَكْعَتَيِ الْفَجْرِ ، فَإِنْ كُنْتُ مُسْتَيْقِظَةً حَدَّثَنِي ، وَإِنْ كُنْتُ نَائِمَةً اضْطَجَعَ حَتَّى يَقُومَ لِلصَّلاةِ "
Lady Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) would perform the two rak'ahs (Sunnah) of Fajr, then if I was awake, he would talk with me, and if I was asleep, he would lie down until the (obligatory) prayer stood.
