ANSWER:

You should tell them that jinn inhabits places of sins and where people do not pray as the angels abandons such places. 

My cousin texted me saying that she thinks her room is “haunted”, that things move around and such. Her and her family don’t pray, listen to music, etc. I have previously advised them many times with salah, Quran, and leaving the haram. However, they ignore. Yet they continuously say they have jinns and ask me for a solution. should I instruct them to do salah or ruqya?
