Disagreements are a fact of life. Disagreements can arise between siblings, close family members and friends. It is human nature to disagree. But, Allāh and His Rasul ﷺ in the Qur’an and hadīth do not teach us to remove all disagreements. What they have taught us is how to manage disagreements. When we disagree, we are taught to confine our disagreements to the original dispute. There is no vendetta in Islam and we do not go beyond the limits of our original disagreement. For example, if we have a disagreement over money, it should be limited to being over money only. However, we tend not to limit it to just that issue but we make it about the person himself, his family and so on. This is going beyond the limit. This is how disputes lead to hostility. This is not the behaviour of a Mu’min.
