We will cast terror into the hearts of the disbelievers; for that they have associated with God that for which He sent down no authority; their abode shall be the fire; evil is the abode of the evildoers.
God (سبحانه) designated our Prophet ﷺ to cast terror (ruʿb) from Him into the hearts of His enemies. [The Prophet] (عليه السلام) said: “I was helped by terror (ruʿb).” He also follows this way (sunna) with His friends. He puts fear (hayba) of them into hearts. Fear (hayba) and force (qahr) would hardly be right in hearts were it not from Him and used with those who follow falsehood, make false claims, and misrepresent [the truth].
