Az-Zukhruf 43:36

Waman yaAAshu AAan thikri arrahmaninuqayyid lahu shaytanan fahuwa lahu qareen

And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion.

Whoever makes himself blind against the advice of RaHmān, We assign for him a devil who accompanies him all the time.
