Resistible through piety and prayer

Redcap

Folklore holds that a Redcap cannot be fought off by ordinary means, and that the only reliable defense is a text or symbol of Christian faith, such as reciting scripture, brandishing a crucifix, or displaying a passage from the Bible, at which the creature is said to shriek and vanish, sometimes leaving behind a single tooth or claw as the only proof of the encounter.

Qareen

Hadith accounts, including reports attributed to the Prophet Muhammad, describe every person as having a jinn companion charged with inciting them toward wrongdoing, though the same accounts note that a Qareen can be overcome or made to submit through piety and remembrance of God (dhikr), so its influence is regarded as resistible rather than absolute.
