البيهقي:٢٩٣٤أَخْبَرَنَا عَلِيُّ بْنُ أَحْمَدَ الْمُقْرِئُ بِبَغْدَادَ أنبأ أَحْمَدُ بْنُ سَلْمَانَ ثنا إِبْرَاهِيمُ بْنُ إِسْحَاقَ ثنا أَبُو سَلَمَةَ ثنا حَمَّادٌ أنبأ عَبْدُ اللهِ بْنُ عَوْنٍ عَنْ رَجَاءِ بْنِ حَيْوَةَ عَنْ مَحْمُودِ بْنِ الرَّبِيعِ قَالَ سَمِعْتُ عُبَادَةَ بْنَ الصَّامِتِ ؓ يَقْرَأُ خَلْفَ الْإِمَامِ فَقُلْتُ لَهُ تَقْرَأُ خَلْفَ الْإِمَامِ؟ فَقَالَ
