The Devils Deception by Imam Ibn AL-Jawzi

Chapter Five: Devil's Deception in Matters of Creed (al- 'aqti'id) and Religion
Some of them said: 'The Darkness' produces devils, and 'The Light'
produces angels. Neither one of the two can overcome the other.
Al-NiibakhI mentioned many of their silly beliefs regarding the
Light and Darkness, such as believing that Man has ordered them

So we are left with the first option, that both are able. Now imagine
