with more terror than a wolf fleeing from a lion.

Worship and obedience illuminate the heart and make it strong and steadfast, until it becomes like a clear mirror, shining with light.

When Shaytaan draws close, he is struck by its light like those who try to eavesdrop [in the heavens] are struck by the shooting stars, and Shaytaan flees from this heart with more terror than a wolf fleeing from a lion.

ibnul qayyim in Al-Jawaab al-Kaafi, p. 64
