Dear Muslim Brothers and Sisters Im a practising muslim I really need your guidence. I am suffering from very bad condition bad toughts constently comes about Allah such as nauzubillah there is no Allah nauzubillah no prophet. Anything which i learn about islam automatically in my heart comes that nauzubillah its lie. when i think about creatures of allah, the Sun, the moon and on meaning of verses of Quran same toughts come into my heart then I say au zu billah like this during zikr and Salah same situation happen.I keep checking my heart every time but i do not satisfy. I search alot but i couldnt find similar issue as mine. almost five years ago i was non practising muslim then suddenly I started practising islam i was performing 5 times prayer at mosque also reciting and zikr but after a few days evil toughts started in my head and due which i got mentel problem. My father took me to the doctor. The doctor said that i have mentel disorder called OCD after that i stopped practsing islam and started working during this i did not experiance evil toughts but i doubting in daily life issues such as checking again and again the door etc. Now 10 days ago I intend to start practising islam again unfortunately again same problem started I always feel very sad and fear I also doubt in daily issues such as weather the door i locked or no i check again and again etc but this time i intend that i will not stop practising islam Inshallah sometimes I think my iman is weak or its shaitan who wispers in my head or could be because of mental problem (OCD) Please suggest how to get rid of these toughts sorry for weak english
