Do I remain within the fold of Islam despite the presence of obsessive doubts and polytheistic imaginings, and is performing ghusl with the intention of renewing my entry into Islam and uttering the Shahada before the ghusl for major ritual impurity a valid act?

"The whispers (waswas) have greatly affected you due to the weakness of your connection with Allah. What you did is not disbelief (kufr), but rather a transgression (fisq) that necessitates repentance from viewing forbidden things and neglecting prayer. We advise you to ignore these whispers and not dwell on them, as their consequences are dire. Your ghusl (ritual bath) with the intention of entering Islam is incorrect, so do not repeat it."
