حَدَّثَنَا إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ، حَدَّثَنَا مَعْنٌ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي نُعَيْمٍ، وَهْبِ بْنِ كَيْسَانَ أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ مَنْ صَلَّى رَكْعَةً لَمْ يَقْرَأْ فِيهَا بِأُمِّ الْقُرْآنِ فَلَمْ يُصَلِّ إِلاَّ أَنْ يَكُونَ وَرَاءَ الإِمَامِ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
