Hiranyakashapu got a boon from Lord Brahma that neither man nor animal can kill him neither in the house nor out of the house and neither during the day time nor night.
As per his boon Vishnu appeared as Narasimha swamy (Half-animal and half-man) to kill the demon in the evening (sandhya kaal) at the door of his house. Prahlada was the son of Hiranyakashapu and the devotee of Lord Vishnu. Hiranyakashapu wanted to kill his son because of his devotion to Lord Vishnu.
