البيهقي:١٦٩٦ – أَخْبَرَنَا أَبُو عَمْرٍو مُحَمَّدُ بْنُ عَبْدِ اللهِ الْأَدِيبُ أنبأ أَبُو بَكْرٍ الْإِسْمَاعِيلِيُّ ثنا الْحَسَنُ بْنُ سُفْيَانَ ثنا فَيَّاضُ بْنُ زُهَيْرٍ ثنا عَبْدُ الرَّزَّاقِ أنبأ مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ عُرْوَةَ عَنْ عَائِشَةَ قَالَتْ

فُرِضَتِ الصَّلَاةُ عَلَى النَّبِيِّ ﷺ بِمَكَّةَ رَكْعَتَيْنِ رَكْعَتَيْنِ فَلَمَّا خَرَجَ إِلَى الْمَدِينَةِ فُرِضَتْ أَرْبَعًا وَأُقِرَّتْ صَلَاةُ السَّفَرِ رَكْعَتَيْنِ  

أَخْرَجَهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنْ مُسَدَّدٍ عَنْ يَزِيدَ بْنِ زُرَيْعٍ عَنْ مَعْمَرٍ قَالَ وَتَابَعَهُ عَبْدُ الرَّزَّاقِ عَنْ مَعْمَرٍ قَالَ الشَّيْخُ وَهَذَا التَّقْيِيدُ تَفَرَّدَ بِهِ مَعْمَرُ بْنُ رَاشِدٍ عَنِ الزُّهْرِيِّ وَسَائِرُ الثِّقَاتِ أَطْلَقُوهُ
