Exposing someone's wrongdoing is not always the best or only approach. While it may be necessary in certain situations, alternative approaches like reconciliation, mediation, or providing guidance and support can often yield better results. Islam encourages individuals to promote positive change, guide others towards improvement, and seek forgiveness and reconciliation whenever possible. It is important to consider the overall impact, the potential for harm, and the effectiveness of exposing someone's wrongdoing before deciding on the appropriate course of action.
