Hiranyakashipu immediately called for Prahlad and asked him for what reason he did as such. Prahlad answered him that Lord Vishnu is the defender of the entire universe that is the reason he pray to him. The student at the ashram was likewise affected by Prahlad and adored Lord Vishnu like him. Hiranyakashipu asked his son what you like the most. Prahald replied him that I love to praise the Lord Vishnu and to recite his namam all the time. Again he asked his son who is the strongest in the universe , for that Prahlad replied Lord Vishnu is the Strongest in the world since he is the protector of this universe.

Till now Hiranyakashipu had controlled his outrage. He lost his temper and requested his guards to toxic substance Prahlad. Prahlad drank the offered glass loaded with toxic substance yet it didn't affect him. Everybody was shocked to see the wonder.

At that point Hiranyakashipu requested that Prahlad must be attached to a huge tremble and tossed into the ocean to suffocate. Anyway, by and by a supernatural occurrence happened. The ropes that bound him came free and he left the ocean waters by reciting Lord Vishnu's name. At that point Prahlad was made to sit on a smoldering fire. However, miraculously, the flares touched his body and were extinguished. Prahlad sat unscathed.

After that Hiranyakashipu attached Prahlad to a pillar. He grabbed the sword to remove his head. As he was going to utilize his sword, the Earth stun viciously. The pillar broke into pieces and a peculiar animal showed up. He was the Narasimha Avatar of Lord Vishnu with Half-Lion and Half-human. He picked Hiranyakashipu and laid him on his laps and situated himself at the entryway post. Anyhow, Hiranyakashipu yelled, "Whoever you will be, you can't murder me. I have such a shelter."

Narasimha thundered, "It is neither day nor night, its evening not day or night. You are on my lap which is neither on earth nor in the sky. I am neither human, nor god, nor an Asura or a daitya. I am not utilizing any instruments or weapons to slaughter you. I am utilizing my sharp nails to murder you. So I can murder you without demonstrating any disregard to Lord Brahma's shelter."Thus, Lord Vishnu's Narasimha Avatar murdered Hiranyakashipu.
