It is difficult for a soul that desires the life of this world, so that it will increase obedience, close actions, divine knowledge, and constant progress with the breath, so it is difficult for it to leave this worldly life, and for this reason it is called jihad against the two groups. As for those who strive for the sake of God, which is the path to God, that is, to reaching Him from His being a god, it is jihad. In order to gain knowledge of the level from which the world and the rulings appeared in it and from it, the caliphs on earth are among us. They have in these paths as much hardship as the traveler experiences on his fearful path, for he is in the process of exposing himself in traveling in it to the destruction of his wealth and his life, the loss of his children and the loss of his acquaintances. God Almighty said: And they strive with their wealth and their lives for the sake of God and said: They fight in the way of God, so they kill and are killed.
