Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 45

Sanskrit:

अयं ममेष्टो दयितोऽनुवर्तीमयाभयं दत्तममुष्य देव ।सम्पाद्यतां तद् भवत: प्रसादोयथा हि ते दैत्यपतौ प्रसाद: ॥ ४५ ॥

ITRANS:

ayaṁ mameṣṭo dayito ’nuvartīmayābhayaṁ dattam amuṣya devasampādyatāṁ tad bhavataḥ prasādoyathā hi te daitya-patau prasādaḥ

Translation:

This Bāṇāsura is my dear and faithful follower, and I have awarded him freedom from fear. Therefore, my Lord, please grant him Your mercy, just as You showed mercy to Prahlāda, the lord of the demons.

Purport:

Lord Śiva feels inclined to help Bāṇāsura because the demon showed great devotion to Lord Śiva when he provided musical accompaniment for Śiva’s tāṇḍava dance. Another reason Bāṇa is an object of Lord Śiva’s favor is that he is a descendant of the great devotees Prahlāda and Bali.
