Śrīmad-Bhāgavatam · Text 7.4.28
Who is speaking and story frame
निर्वैराय प्रशान्ताय स्वसुताय महात्मने ।
प्रह्रादाय यदा द्रुह्येद्धनिष्येऽपि वरोर्जितम् ॥ २८ ॥
nirvairāya praśāntāya
sva-sutāya mahātmane
prahrādāya yadā druhyed
dhaniṣye ’pi varorjitam
When Hiraṇyakaśipu teases the great devotee Prahlāda, his own son, who is peaceful and sober and who has no enemy, I shall kill Hiraṇyakaśipu immediately, despite the benedictions of Brahmā.
