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  

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] "I heard a man reciting a verse differently from the way the Messenger of Allah ﷺ recited it. So I took his hand and went with him to the Prophet ﷺ . The Prophet ﷺ said, 'Both of you have done well.' He (the man) said, 'But he became angry until anger could be seen on his face.' Shu'bah (narrator of the hadeeth) said, 'I think he (the Prophet) said, 'Do not differ, for those before you differed and were destroyed.'' "  

سَمِعْتُ رَجُلًا يَقْرَأُ آيَةً عَلَى غَيْرِ مَا أَقْرَأَنِي رَسُولُ اللهِ ﷺ فَأَخَذْتُ بِيَدِهِ فَأَتَيْتُ بِهِ النَّبِيَّ ﷺ فَقَالَ كِلَاكُمَا قَدْ أَحْسَنَ قَالَ وَغَضِبَ حَتَّى عُرِفَ الْغَضَبُ فِي وَجْهِهِ قَالَ شُعْبَةُ أَكْبَرُ ظَنِّي أَنَّهُ قَالَ لَا تَخْتَلِفُوا فَإِنَّ مَنْ قَبْلَكُمُ اخْتَلَفُوا فِيهِ فَهَلَكُوا  

[Machine] I heard the Messenger of Allah ﷺ reciting something other than what was written in front of me. So, I held his hand and went to the Prophet ﷺ . I saw that the face of the Prophet ﷺ had changed, and he said, "You both are good, do not differ in it, for indeed those who came before you differed in it."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقْرَأُ غَيْرَهَا فَأَخَذْتُ بِيَدِهِ فَأَتَيْتُ بِهِ النَّبِيَّ ﷺ فَرَأَيْتُ النَّبِيَّ ﷺ تَغَيَّرَ وَجْهُهُ فَقَالَ «كِلَاكُمَا مُحْسِنٌ لَا تَخْتَلِفُوا فِيهِ فَإِنَّ مَنْ كَانَ قَبْلَكُمُ اخْتَلَفُوا فِيهِ»
