﴾And whoever is blinded from remembrance of Ar-Raḥmān – We appoint for him a devil, and he is to him a companion.﴿ az-Zukhruf:36

A heart void of remembrance of Allāh is easily penetrable by and pliable to the whisperings of Shayṭān.

A person becomes acceptant of bad company when his heart is parched for Dhikr.
