The Promised Messiahas said: “When Muslims are encouraged and exhorted to proclaim the Muslim creed, it is for the very that without it, one can develop no courage at all. When a man says لَا إِلَٰهَ إِلَّا اللَّٰهُ (There is none worthy of worship except Allah), he deems the power and strength of all human beings and things, and of all rulers, officials, enemies and friends to be insignificant, and looks to Allah alone. Such a person deems all that is besides God to be worthless. And so, a person of this nature acts with bravery and courage, and nothing and no one is able to frighten them.”
