Arabic Text
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، صلى الله عليه وسلم خِلاَفَهَا، فَأَخَذْتُ بِيَدِهِ، فَأَتَيْتُ بِهِ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ " كِلاَكُمَا مُحْسِنٌ ". قَالَ شُعْبَةُ أَظُنُّهُ قَالَ " لاَ تَخْتَلِفُوا فَإِنَّ مَنْ كَانَ قَبْلَكُمُ اخْتَلَفُوا فَهَلَكُوا ".
English Translation
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). "
This hadith is from Sahih al-Bukhari, the most rigorously authenticated collection in Islamic scholarship. No editorial opinion is added.
