If a person has faith in his heart but he/she utters words of kufr both intentionally or unintentionally does that person become a kafir ?
I want to know if a person utters words of kufr intentionally or unintentionally does that person become a kafir and he/ she has to enter islam again by reciting the shahadah again.
I have so much waswas that whenever I talk I think I uttered words of kufr and I say the shahadah again and again. This is making me so worried that may be I am doomed to hell because I uttered words of kufr and don't know what to do.
Some example below of my situation: By words of kufr I mean any statement that makes a person leave islam. For example when I say Shahadah I say there is no one who is worthy of worship except Allah and that Muhammad S.A.W is the last and final messenger of Allah.(English translation of the Shahdah in Arabic). But when I say Muhammad (S.A.W) I have waswas who is God and it seems like naozobillah as if I said God to Muhammad . This is making me sick now. Even when I talk I use simple words like 'is' 'me' etc and then waswas comes who is God and it feels like if I said God to someone else or myself respectively.
