Śrīmad-Bhāgavatam
[Canto 7, Ch. 10]
The Lord advised Prahlāda to perform sacrifices through  bhakti-yoga , for this is the duty of a king.
Prahlāda Mahārāja accepted whatever the Lord had offered him, and he prayed for the Lord to deliver his father. In response to this prayer, the Lord assured him that in the family of such a pure devotee as he, not only the devotee's father but his forefathers for twenty-one generations are liberated. The Lord also asked Prahlāda to perform the ritualistic ceremonies appropriate after his father's death.
Then Lord Brahmā, who was also present, offered many prayers to the Lord, expressing his obligation to the Lord for having offered benedictions to Prahlāda Mahārāja. The Lord advised Lord Brahmā not to offer benedictions to  asuras  as he had to Hiraṇyakaśipu, for such benedictions indulge them. Then Lord Nṛsiṁhadeva disappeared. On that day, Prahlāda Mahārāja was installed on the throne of the world by Lord Brahmā and Śukrācārya.
Thus Nārada Muni described the character of Prahlāda Mahārāja for Yudhiṣṭhira Mahārāja, and he further described the killing of Rāvaṇa by Lord Rāmacandra and the killing of Śiśupāla and Dantavakra in Dvāpara-yuga. Śiśupāla, of course, had merged into the existence of the Lord and thus achieved  sāyujya-mukti . Nārada Muni praised Yudhiṣṭhira Mahārāja because the Supreme Lord, Kṛṣṇa, was the greatest well-wisher and friend of the Pāṇḍavas and almost always stayed in their house. Thus the fortune of the Pāṇḍavas was greater than that of Prahlāda Mahārāja.
Later, Nārada Muni described how the demon Maya Dānava constructed Tripura for the demons, who became very powerful and defeated the demigods. Because of this defeat, Lord Rudra, Śiva, dismantled Tripura; thus he became famous as Tripurāri. For this, Rudra is very much appreciated and worshiped by the demigods. This narration occurs at the end of the chapter.
