The Prophet ﷺ says whoever loves for Allāh ﷻ, keeps distance for Allāh ﷻ, gives for Allāh ﷻ, takes for Allāh ﷻ, and marries for Allāh ﷻ is a true believer. When īmān is complete, a person has no worry and no fear, even if the world collapses, because he knows everything happens by the will of Allāh ﷻ. People today are afraid and forget Allāh ﷻ, but what Allāh ﷻ wills cannot be prevented. Fear only Allāh ﷻ. That is enough.
