Narrated `Abdullah: The Prophet said, "Recite (and study) the Qur'an as long as you agree about its interpretation, but if you have any difference of opinion (as regards to its interpretation and meaning) then you should stop reciting it (for the time being).
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادٌ، عَنْ أَبِي عِمْرَانَ الْجَوْنِيِّ، عَنْ جُنْدَبِ بْنِ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " اقْرَءُوا الْقُرْآنَ مَا ائْتَلَفَتْ قُلُوبُكُمْ، فَإِذَا اخْتَلَفْتُمْ فَقُومُوا عَنْهُ " .
