My brother and I once sat in a gathering that I would not exchange for the finest of red camels. My brother and I came along, and there we found a group of elder Companions of the Messenger of Allah ﷺ sitting at one of his doors. We did not wish to break up their circle, so we sat off to the side. They began discussing a verse of the Quran and fell into dispute over it, until their voices grew loud.The Messenger of Allah ﷺ came out angry, his face flushed red. He threw dust at them and said, "Hold back, my people. It was by this that the nations before you were destroyed, through their disagreement with their prophets and their pitting of scriptures against one another. The Quran was not revealed so that one part would contradict another. Rather, one part confirms another. Whatever of it you understand, act upon it, and whatever of it you do not know, refer it to one who does."
لقد جلست أنا وأخي مجلسا ما أحب أن لي به حمر النعم، أقبلت أنا وأخي، وإذا مشيخة من صحابة رسول الله ﷺ جلس عند باب من أبوابه، فكرهنا أن نفرق بينهم، فجلسنا حجرة، إذ ذكروا آية من القرآن، فتماروا فيها، حتى ارتفعت أصواتهم، فخرج رسول الله ﷺ مغضبا، قد احمر وجهه، يرميهم بالتراب، ويقول: مهلا يا قوم، بهذا أهلكت الأمم من قبلكم باختلافهم على أنبيائهم، وضربهم الكتب بعضها ببعض، إن القرآن لم ينزل يكذب بعضه بعضا، بل يصدق بعضه بعضا، فما عرفتم منه، فاعملوا به، وما جهلتم منه، فردوه إلى عالمه.
Ahmad narrated it (6702) from Anas bin Iyad, who said, Abu Hazim narrated to us, from Amr bin Shuayb, from his father, from his grandfather, and he mentioned it. Its isnad is hasan because of Amr bin Shuayb, for he is hasan al-hadith, and likewise his father. The Prophet ﷺ warned against disputing over the Noble Quran, as will be seen in the hadith that follows.
