All of us have good characteristics and a darker side. The most important battle we face daily is getting rid of the evil desires we all possess.
This is referred to as a spiritual jihad or a battle. Umar ibn Abdul Aziz (RA) said “the best form of jihad is the jihad against desires.” Winning this battle means we have to cultivate true sincerity to Allah!
The most important fight in this life is not against other people but against those desires and the devils that manipulate them!
