In Letter (72), Imam Ali (a.s.) provides important advice to Abdullah Ibn Abbas (may Allah have mercy on him) that highlights the realities of human life. This letter was written during a time when the Islamic community was facing various challenges, and through this letter, Imam Ali (a.s.) aimed to enlighten his followers about patience, destiny, and the transient nature of the world.

Imam Ali (a.s.) states that one cannot go beyond the limits of their life and cannot achieve what is not in their destiny. This is a crucial philosophy that balances the relationship between fate and human efforts. It implies that while individuals should strive for their goals, they must also recognize that some things are beyond their predetermined fate.

He also mentions that life is divided into two days: one day in favor of a person and the other against them. This statement serves as a reminder that life encompasses both joy and sorrow, and one must face these with patience and resilience.

This imparts an important lesson about adopting a realistic attitude towards one’s strengths and weaknesses.

The spiritual and practical teachings of this letter guide us to accept our destiny and strive accordingly. To confront the challenges that life presents, we need patience and perseverance, and we must understand that some matters lie beyond our control.
