Detailed Explanation — Wisdom (326): He said to his secretary Ubayd Allah Ibn Abi Rafi Put couch in the medicine, and keep the tongue of the pen long. Leave more space between the lines and write the letters together, this is all for the decoration of the letter.

In Wisdom (326), Imam Ali (peace be upon him) states that the age after which Allah does not accept a person's excuses is sixty years. This wisdom highlights a crucial aspect of human life. The historical context of this saying relates to a time when the moral and spiritual responsibilities of individuals within the Islamic community were being emphasized.

The main theme of this wisdom is the significance of human age and how one utilizes it. Sixty years is chosen as it represents an age where individuals must account for their actions. After this age, if a person presents excuses for their sins, Allah does not accept them. This conveys a stern yet realistic message that individuals should value every moment of their lives.

Key phrases in this wisdom, such as "does not accept excuses," indicate that there is a limit to Allah's mercy and forgiveness, and individuals should strive to perform good deeds throughout their lives.

The moral and spiritual lessons here emphasize that one should not waste the precious moments of life. We should aim to improve ourselves every day so that we may stand before our Lord with honor. Practically, this reminds us to plan our lives wisely and increase our good deeds, especially as we approach this significant age.
