Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah — Hadith #7364
اقْرَءُوا الْقُرْآنَ مَا ائْتَلَفَتْ قُلُوبُكُمْ فَإِذَا اخْتَلَفْتُمْ فَقُومُوا عَنْهُ "
The chain (isnad) appears to be missing from this record. Under review.
Allah's Messenger (ﷺ) said, "Recite (and study) the Qur'an as long as you are in agreement as to its interpretation and meanings, but when you have differences regarding its interpretation and meanings, then you should stop reciting it (for the time being.) (See Hadith No 581, Vol. 6)
اقْرَءُوا الْقُرْآنَ مَا ائْتَلَفَتْ قُلُوبُكُمْ فَإِذَا اخْتَلَفْتُمْ فَقُومُوا عَنْهُ "
