Should you enter this straight path, which is the path of Islam, then until the end of your lives, all those that have recited their mandatory prayers several times everyday and have implored “…Guide us on the Straight Path…” shall be rightly guided. When he is guided, he shall be guided until the end of his life. The important thing is that a person enters that path that he must traverse—be the spiritual journey or material journey that is also spiritual in one context. This means that after a government has become Islamic, it is wholly based on spirituality.
