Calling your Muslim brother a disbeliever?
Hadith 481
295- وبه: أن رسول الله قال: ”أيما رجل قال لأخيه: كافر، فقد باء بها أحدهما.“
And with the same chain of narration, it is narrated from (Sayyiduna Ibn Umar, may Allah be pleased with them both) that the Messenger of Allah, peace and blessings be upon him, said: "If a man calls his (Muslim) brother a disbeliever, then this (verdict) returns to one of them, that is, one of the two becomes a disbeliever."
