Recite the Qur’an as long as your hearts are harmonious, but if you diverge, then move away from it

This Hadīth means that the Muslims should recite the Qur’an together as long as they agree on its interpretation. However, if they disagree in understanding its meanings, then they should stop reciting it lest this disagreement should lead to evil. Another possible meaning: stick to the meanings of the Qur’an which are not prone to different interpretations. If you come across meanings which can be interpreted differently and cause dispute, avoid debating and arguing regarding them.

This could also be an instruction to recite the Qur’an as long as one's heart is inclined to do so. If the heart feels bored or tired, then recitation should be left until the heart becomes fresh and active again. The same command was given concerning the prayer. The first interpretation, however, seems more probable.
