Disturbed with bad thoughts about allah and islam and aulia allah

I am suffering with lot of evil and bad thoughts about all the things on which i have utmost faith. I was never like this it just started a month ago. i Praise allah and rasool allah with my heart and has got utmost fear and love for them. from few days i am getting wierd thoughts about them which makes me feel very guilty. i immediately seek for forgiveness from allah but iam really not happy with this kind of things happening in my life. i am also getting thoughts about all the aulia allah. my situation is very bad i am feeling very scared to take the name of any aulia allah thinking that some bad thought might come up with it. when i am in namaz i am really getting scared to think of anything and also to make dua. when i am praying dua some thoughts are really overruling my words distracting me badly. I request you please help me and provide a solution to this problem.
