Sahih al-Bukhari · Book 66: Virtues of the Qur'an · Recite the Qur'an together as long as you agree about its interpretation
Narrated `Abdullah:
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 " .
The Prophet (ﷺ) 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).
