It is narrated from Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with him), he says: There was a gathering between me and my brother, sitting in which was more valuable to me than red camels. The detail is that my brother and I came and found a group of senior Companions sitting at the door of the Prophet (peace and blessings be upon him). We did not consider it appropriate to separate them and sat in a corner. They mentioned a verse and then began to argue about it, until their voices were raised. Meanwhile, the Noble Prophet (peace and blessings be upon him) came to them, while he was in a state of anger and his blessed face had become red. The Prophet (peace and blessings be upon him) threw dust on those Companions and said: O people! Stop! The previous nations were destroyed only because of this disagreement; they differed with their Prophets and set parts of the Book against other parts. Surely, the Qur’an was not revealed in such a way that one part contradicts another; rather, one part confirms the other. So, act upon the part you have knowledge of, and as for the part you do not know, refer it to those who know it.
