The ruling on cursing Iblis when one falls into error

Question:
Is there any basis for the phrase people use when they say to someone, "May Allah curse your Iblis"?

Answer:

Iblis rejoices when you curse him and blame him; he rejoices in this. Yes, he says, "I led him astray." When you curse him and blame Iblis, he rejoices and says, "I led the son of Adam astray." But you must repent, seek forgiveness, and seek refuge from Shaytan and from the devils of mankind and jinn. Yes.
