أبو داود:١٣٩٥ – حَدَّثَنَا نُوحُ بْنُ حَبِيبٍ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنْ سِمَاكِ بْنِ الْفَضْلِ عَنْ وَهْبِ بْنِ مُنَبِّهٍ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو

أَنَّهُ سَأَلَ النَّبِيَّ ﷺ فِي كَمْ يَقْرَأُ الْقُرْآنَ قَالَ فِي أَرْبَعِينَ يَوْمًا ثُمَّ قَالَ فِي شَهْرٍ ثُمَّ قَالَ فِي عِشْرِينَ ثُمَّ قَالَ فِي خَمْسَ عَشْرَةَ ثُمَّ قَالَ فِي عَشْرٍ ثُمَّ قَالَ فِي سَبْعٍ لَمْ يَنْزِلْ مِنْ سَبْعٍ
