Vishnu Puran 32 (with English subtitle)

Shukracharya orders his sons for the birth of kritya (black magic). When she fails in killing Prahlad, kills Kshand and Amark. When Shukracharya blames Prahlad for the death of his sons, he pleeds God Vishnu to restore the life of his teachers. God Vishnu as usual honors his prayer. Hiranyakashyapu declares Ahalad as his prince and expects the news of Prahlad's death in vain.
