This letter is addressed by Imam Ali (a.s) to Abdullah Ibn Abbas following the martyrdom of Muhammad Ibn Abi Bakr. This event took place during a time when enemies invaded Egypt, resulting in the martyrdom of Muhammad Ibn Abi Bakr. The letter reflects the political and military context of the time, where Imam Ali faced the weakness and apathy of his supporters.

In this letter, Imam Ali (a.s) expresses sorrow over the martyrdom of Muhammad Ibn Abi Bakr, recalling him as a loyal and brave companion. He mentions that he had repeatedly called upon people to assist Muhammad Ibn Abi Bakr, but many failed to respond. This highlights the political apathy and disinterest of the people during that period.

Imam Ali (a.s) prays to Allah for deliverance from the hands of those who did not support him. He also expresses his desire for martyrdom, which signifies his courage and readiness to face the enemy. This serves as an important message that one should fight for the truth without fearing for their life.

A key lesson from this letter is the importance of understanding one's responsibilities and being ready to help others. Imam Ali's writing teaches us that sometimes one must be willing to sacrifice their life, but never retreat from the path of truth.
