Abdullah ibn Amr reported: He heard the shouting of two men disputing over a verse. The Messenger of Allah, peace and blessings be upon him, came out to us and we could see the anger on his face, and he said, “Verily, those before you were ruined by their differences over the Book.”

عَنْ عَبْد اللَّهِ بْن عَمْرو أنه فَسَمِعَ أَصْوَاتَ رَجُلَيْنِ اخْتَلَفَا فِي آيَةٍ فَخَرَجَ عَلَيْنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُعْرَفُ فِي وَجْهِهِ الْغَضَبُ فَقَالَ إِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِاخْتِلَافِهِمْ فِي الْكِتَابِ
