I heard a man reciting a verse (of the Holy Qur'an) but I had heard the Prophet ﷺ reciting it differently. So, I caught hold of the man by the hand and took him to Messenger of Allah ﷺ who said, "Both of you are right." Shuʿba, the sub-narrator said, "I think he said to them, "Don't differ, for the nations before you differed and perished (because of their differences). "  

سَمِعْتُ مِنَ النَّبِيِّ ﷺ خِلاَفَهَا فَأَخَذْتُ بِيَدِهِ فَأَتَيْتُ بِهِ رَسُولَ اللَّهِ ﷺ فَقَالَ كِلاَكُمَا مُحْسِنٌ قَالَ شُعْبَةُ أَظُنُّهُ قَالَ لاَ تَخْتَلِفُوا فَإِنَّ مَنْ كَانَ قَبْلَكُمُ اخْتَلَفُوا فَهَلَكُوا  

I heard a person reciting a (Qur'anic) Verse in a certain way, and I had heard the Prophet ﷺ reciting the same Verse in a different way. So I took him to the Prophet ﷺ and informed him of that but I noticed the sign of disapproval on his face, and then he said, "Both of you are correct, so don't differ, for the nations before you differed, so they were destroyed."  

وَسَمِعْتُ النَّبِيَّ ﷺ يَقْرَأُ خِلاَفَهَا فَجِئْتُ بِهِ النَّبِيَّ ﷺ فَأَخْبَرْتُهُ فَعَرَفْتُ فِي وَجْهِهِ الْكَرَاهِيَةَ وَقَالَ كِلاَكُمَا مُحْسِنٌ وَلاَ تَخْتَلِفُوا فَإِنَّ مَنْ كَانَ قَبْلَكُمُ اخْتَلَفُوا فَهَلَكُوا  

That he heard a man reciting a Quranic Verse which he had heard the Prophet ﷺ reciting in a different way. So he took that man to the Prophet (and told him the story). The Prophet ﷺ said, "Both of you are reciting in a correct way, so carry on reciting." The Prophet ﷺ further added, "The nations which were before you were destroyed (by Allah) because they differed."  

سَمِعَ النَّبِيَّ ﷺ خِلاَفَهَا فَأَخَذْتُ بِيَدِهِ فَانْطَلَقْتُ بِهِ إِلَى النَّبِيِّ ﷺ فَقَالَ كِلاَكُمَا مُحْسِنٌ فَاقْرَآ أَكْبَرُ عِلْمِي قَالَ فَإِنَّ مَنْ كَانَ قَبْلَكُمُ اخْتَلَفُوا فَأَهْلَكَهُمْ  

[Machine] "And I heard from the Messenger of Allah ﷺ other than it (this). So I brought it to the Messenger of Allah ﷺ and the face of the Messenger of Allah ﷺ changed or I recognized disapproval in the face of the Messenger of Allah ﷺ . So the Messenger of Allah ﷺ said, 'Both of you are doing well. Indeed, those before you differed in it and it destroyed them.'"  

وَسَمِعْتُ مِنْ رَسُولِ اللهِ ﷺ غَيْرَهَا فَأَتَيْتُ بِهِ رَسُولَ اللهِ ﷺ فَتَغَيَّرَ وَجْهُ رَسُولِ اللهِ ﷺ أَوْ عَرَفْتُ فِي وَجْهِ رَسُولِ اللهِ ﷺ الْكَرَاهِيَةَ فَقَالَ رَسُولُ اللهِ ﷺ كِلَاكُمَا مُحْسِنٌ إِنَّ مَنْ قَبْلَكُمِ اخْتَلَفُوا فِيهِ فَأَهْلَكَهُمْ
