Sahih Muslim , Book 34, Hadith 6444 (USC-MSA) ⓘ

Jundub b. 'Abdullah al-Bajali reported Allah's Messenger as saying: Recite the Qur'an as long as your hearts agree to do so, and when you feel variance between them (between your hearts and tongues), then get up (and leave its recital for the time being).

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو قُدَامَةَ الْحَارِثُ بْنُ عُبَيْدٍ، عَنْ أَبِي عِمْرَانَ، عَنْ جُنْدُبِ بْنِ عَبْدِ اللَّهِ الْبَجَلِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ اقْرَءُوا الْقُرْآنَ مَا ائْتَلَفَتْ عَلَيْهِ قُلُوبُكُمْ فَإِذَا اخْتَلَفْتُمْ فِيهِ فَقُومُوا ‏" ‏ ‏.‏
