Narrated by Sayyiduna Jundub bin Abdullah (may Allah be pleased with him) from the Noble Prophet (peace and blessings of Allah be upon him) that he (peace be upon him) said: "Recite the Noble Qur'an as long as your heart is inclined towards it, and when you begin to differ among yourselves, then stop reciting the Qur'an." (That is, due to lack of interest, the words may get mixed up or recited incorrectly.)
