Should one be concerned about the obsessive whisperings (waswas) regarding directing prayer or prostration towards hanging pictures while remembering Allah?

We advise you to dismiss these whisperings and pay no attention to them. Affirm with certainty that your prayer and prostration are for Allah alone, who has no partner. Close this door on yourself so that Satan does not open it for you. It is disliked to pray towards images because they distract theer and divert him from devotion.
