Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 1
श्रीनारद उवाचएवं वृत: शतधृतिर्हिरण्यकशिपोरथ ।प्रादात्तत्तपसा प्रीतो वरांस्तस्य सुदुर्लभान् ॥ १ ॥
śrī-nārada uvācaevaṁ vṛtaḥ śata-dhṛtirhiraṇyakaśipor athaprādāt tat-tapasā prītovarāṁs tasya sudurlabhān
Nārada Muni continued: Lord Brahmā was very much satisfied by Hiraṇyakaśipu’s austerities, which were difficult to perform. Therefore, when solicited for benedictions, he indeed granted them, although they were rarely to be achieved.
