Detailed Explanation — Wisdom (218): Fear Allah like the fear of a person who left the worldly commitments and turned his feet and started striving for good and walked with a fast pace in this interval of life and in the face of dangers he stepped towards good deeds and kept an eye on his decision and the result of his actions and the destination of the doer.

Wisdom (218) by Imam Ali (a.s.) emphasizes the importance of friendship and highlights the flaws of envy within it. This saying teaches us that in true friendship, there should be no place for jealousy. Envy is a negative emotion that affects the beauty of friendship. During Imam Ali's time, when people lived closely together, it was crucial that friendships were rooted in sincerity and love.

In this wisdom, the phrase "the envy of a friend" signifies a flaw that weakens the bond of friendship. Because of envy, a person cannot rejoice in their friend's achievements; instead, it breeds animosity in their heart. This feeling not only affects friendship but can also have a detrimental impact on one’s spiritual state.

Imam Ali (a.s.) teaches us to celebrate each other's successes in friendship. When we are happy for our friends' accomplishments, it not only strengthens our relationship but also brings us joy and peace. The practical takeaway from this wisdom is that we should fill our hearts with love and happiness instead of envy.

Furthermore, this wisdom reminds us that sincerity is essential in friendships. If we harbor good wishes for our friends, it not only makes us better individuals but also strengthens our relationships. Imam Ali's (a.s.) wisdom aids us in understanding the true spirit of friendship.
