البيهقي:٤٨٨٢أَخْبَرَنَا أَبُو طَاهِرٍ الْفَقِيهُ أنبأ أَبُو حَامِدِ بْنُ بِلَالٍ الْبَزَّارُ ثنا عَبْدُ الرَّحْمَنِ بْنُ بِشْرٍ ثنا وَكِيعٌ عَنِ ابْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُخَفِّفُ رَكْعَتَيِ الْفَجْرِ قَالَ وَقَالَ مِسْعَرٌ عَنْ رَجُلٍ مِنَ الْأَنْصَارِ عَنْ سَعِيدِ بْنِ جُبَيْرٍ كَانَ رَسُولُ اللهِ ﷺ رُبَّمَا أَطَالَ رَكْعَتَيِ الْفَجْرِ  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ عَمْرٍو النَّاقِدِ عَنْ وَكِيعٍ دُونَ رِوَايَةِ مِسْعَرٍ وَإِنَّمَا هِيَ مُنْقَطِعَةٌ وَرَوَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ عَنْ وَكِيعٍ عَنْ سُفْيَانَ عَنْ هِشَامِ بْنِ عُرْوَةَ
