Abdullah ibn Mas’ud reported: A man was reciting a verse which I had heard differently from the Prophet, peace and blessings be upon him. I took his hand and brought him to the Prophet and he said, “Both of your recitations are good. Do not differ, for the nations before you were destroyed by their differences.”

عن عبد الله بن مسعود سَمِعْتُ رَجُلًا قَرَأَ آيَةً سَمِعْتُ مِنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خِلَافَهَا فَأَخَذْتُ بِيَدِهِ فَأَتَيْتُ بِهِ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ كِلَاكُمَا مُحْسِنٌ لَا تَخْتَلِفُوا فَإِنَّ مَنْ كَانَ قَبْلَكُمْ اخْتَلَفُوا فَهَلَكُوا
