I do make wudhu and read Quran I also have been overthinking a lot a worrying about things and idk why I’m also very worried of my Iman lowering. I pray all 5 prays and I read Quran sometimes and I don’t listen to music so idk what more I need to do. I want to stop worrying and I don’t know why I worrying about my iman lowering. I think I have been increasing my iman more recently during ramadan but I’m still scared that it will lower and every time I see disbelievers in the street I get scared I fear what if I become one of them. I don’t know why I feel like this because I know would never do that but I still get uncomfortable when I see them

This is Satan’s whispers with which he wants to destroy you, so do not claim a way for him to do that and do not bother with these whispers as long as you are confident of your belief in God Almighty and in the message of Muhammad, may God’s prayers and peace be upon him and his family
