When one becomes a devotee of Indra, he is certainly a friend to the demigods. Thus the words indra-hadeva-bandhavah are equivocal, for they say, "Your son will kill Indra, but he will be very friendly to the demigods"

Srimad-Bhagavatam

SB Canto 6

The word indra-hā refers to an asura who is always eager to kill Indra. An enemy of Indra is naturally a friend to the asuras, but the word indra-hā also refers to one who follows Indra or who is obedient to him. When one becomes a devotee of Indra, he is certainly a friend to the demigods. Thus the words indra-hādeva-bāndhavaḥ are equivocal, for they say, "Your son will kill Indra, but he will be very friendly to the demigods." If a person actually became a friend of the demigods, he certainly would not be able to kill Indra.

SB 6.18.45, Translation and Purport
