أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدٍ الْقَارِيِّ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ نَامَ عَنْ حِزْبِهِ - أَوْ قَالَ جُزْئِهِ - مِنَ اللَّيْلِ فَقَرَأَهُ فِيمَا بَيْنَ صَلاَةِ الصُّبْحِ إِلَى صَلاَةِ الظُّهْرِ فَكَأَنَّمَا قَرَأَهُ مِنَ اللَّيْلِ " .
