Narrated 'Abdullah:

I heard a man reciting a verse (of the Holy Qur'an) but I had heard the Prophet reciting it differently. So, I caught hold of the man by the hand and took him to Allah's Apostle who said, "Both of you are right." Shu'ba, 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). "

حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، قَالَ عَبْدُ الْمَلِكِ بْنُ مَيْسَرَةَ أَخْبَرَنِي قَالَ سَمِعْتُ النَّزَّالَ، سَمِعْتُ عَبْدَ اللَّهِ، يَقُولُ سَمِعْتُ رَجُلاً، قَرَأَ آيَةً 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 ".
