Reconciliation does not happen if you keep on digging up old dirt. If you wish to resolve a dispute, you should not repeatedly go over what has happened before. You have to bury the past.
In order to reconcile, forgive and forget, and to tolerate others you have to focus on the positives and overlook the negatives. This is what we learn from the Qurʾān and hadīth and this should be our approach in everything.
