البيهقي:٥٥٠٢ – أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللهِ الْحَافِظُ أَخْبَرَنِي أَبُو الْوَلِيدِ ثنا الْحَسَنُ بْنُ سُفْيَانَ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ثنا أَبُو أُسَامَةَ عَنْ عُبَيْدِ اللهِ بْنِ عُمَرَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

أَنَّهُ كَانَ إِذَا صَلَّى مَعَ الْإِمَامِ صَلَّى أَرْبَعًا وَإِذَا صَلَّى وَحْدَهُ صَلَّى رَكْعَتَيْنِ  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ أَبِي بَكْرِ بْنِ أَبِي شَيْبَةَ
