حَدَّثَنَا يَحْيَى بْنُ حَكِيمٍ، حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ، حَدَّثَنَا الْمَسْعُودِيُّ، حَدَّثَنَا زَيْدٌ الْعَمِّيُّ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ اجْتَمَعَ ثَلاَثُونَ بَدْرِيًّا مِنْ أَصْحَابِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالُوا تَعَالَوْا حَتَّى نَقِيسَ قِرَاءَةَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِيمَا لَمْ يَجْهَرْ فِيهِ مِنَ الصَّلاَةِ ‏.‏ فَمَا اخْتَلَفَ مِنْهُمْ رَجُلاَنِ فَقَاسُوا قِرَاءَتَهُ فِي الرَّكْعَةِ الأُولَى مِنَ الظُّهْرِ بِقَدْرِ ثَلاَثِينَ آيَةً وَفِي الرَّكْعَةِ الأُخْرَى قَدْرَ النِّصْفِ مِنْ ذَلِكَ وَقَاسُوا ذَلِكَ فِي صَلاَةِ الْعَصْرِ عَلَى قَدْرِ النِّصْفِ مِنَ الرَّكْعَتَيْنِ الأُخْرَيَيْنِ مِنَ الظُّهْرِ ‏.‏
