I agree with Mirch. And I’d like to share a beautiful hadith about zikr, which is pretty self explanatory in this case:
Hadhrat Ibn Abbas (radiallahu anhu) narrates that Rasulullah (sallallahu alayhi wasallam) said:“Shaitaan sits glued to the heart of man. When man makes the Dhikr of Allah, shaitaan abdicates (moves off); when man is negligent of Allah’s Thikr the shaitaan casts evil whisperings in man.”
(Bukhaari)
This is probably the link Somehowcollide is referring to:
