69) باب الْفَضْلِ فِي قِرَاءَةِ ‏{‏ قُلْ هُوَ اللَّهُ أَحَدٌ ‏}‏

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبِي صَعْصَعَةَ، عَنْ أَبِيهِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَجُلاً، سَمِعَ رَجُلاً، يَقْرَأُ ‏{‏ قُلْ هُوَ اللَّهُ أَحَدٌ ‏}‏ يُرَدِّدُهَا فَلَمَّا أَصْبَحَ جَاءَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَذَكَرَ ذَلِكَ لَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ وَالَّذِي نَفْسِي بِيَدِهِ إِنَّهَا لَتَعْدِلُ ثُلُثَ الْقُرْآنِ ‏"‏ ‏.‏
