Anybody know which ḥadīth my friend is referring to? Something about idle minds being more vulnerable

For context, I was talking about my major depressive disorder with a friend. He mentioned a *ḥadīth*, but said he didn't know the source at the top of his mind, about idle minds being easier to control/attack. I have attached a screenshot of some messages we had exchanged after that conversation in case it helps. Some links that may be useful, but it doesn't seem like these are the exact *ḥadīth* he was referencing: > Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, Satan is lying in wait over the heart of the son of Adam. If he remembers Allah, Satan retreats. If he forgets Allah, Satan will devour his heart; that is the ‘whisperer who retreats.’” (114:4) https://www.abuaminaelias.com/dailyhadithonline/2013/03/20/shaytan-al-waswas-al-khannas/ > Sa’id ibn Jubayr reported: Ibn Abbas, may Allah be pleased with him, said, “Satan is perched over the heart of the son of Adam. If he is unmindful and he forgets, Satan whispers. If he remembers Allah, Satan withdraws.” https://www.abuaminaelias.com/dailyhadithonline/2020/06/02/ibn-abbas-on-khannas/
