Self-esteem refers to how we see ourselves and is shaped by our experiences. High self-esteem is associated with confidence and positive qualities while low self-esteem can lead to negative effects like insecurity and depression. In Islam, faith provides a foundation for high self-esteem by establishing our worth comes from Allah rather than external factors. To improve self-esteem, Muslims can strengthen their faith, develop positive habits, find supportive communities, and avoid basing self-worth on temporary things.
