Srimad Bhagavatam Canto 07, Chapter 08, Text 13

SB 7.8.13

so ’ham vikatthamanasya
 sirah kayad dharami te
gopayeta haris tvadya
 yas te saranam ipsitam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Because you are speaking so much nonsense, I shall now sever your head from your body. Now let me see your most worshipable God come to protect you. I want to see it.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Demons always think that the God of the devotees is fictitious. They think that there is no God and that the so-called religious feeling of devotion to God is but an opiate, a kind of illusion, like the illusions derived from LSD and opium. Hiranyakasipu did not believe Prahlada Maharaja when Prahlada asserted that his Lord is present everywhere. Because Hiranyakasipu, as a typical demon, was convinced that there is no God and that no one could protect Prahlada, he felt encouraged to kill his son. He challenged the idea that the devotee is always protected by the Supreme Lord.
