Is it obligatory to repeat the ghusl and wash clothes and everything that was touched after suspecting the transfer of urine impurity, and is urine pardoned if its quantity is small or dry, and what is the authenticity of the statement that wet purity is not defiled if it meets dry impurity?

Summary: The obsessive whisperings have taken a great toll on you, and your only cure is to completely disregard these whisperings and pay them no mind. You should not have performed ghusl (ritual bath) in the first place; rather, you should have purified only the spot you were certain had become impure. Act upon the principle of purity for every spot you doubt has become impure or to which impurity has transferred. You are permitted to adopt the view of those who pardon a small amount of impurity absolutely, and the view of those who hold that impurity does not transfer from one impure object to another if it comes into contact with it while wet. The person afflicted with obsessive whisperings should adopt the easiest of opinions. You must rule everything you doubt to be impure as pure, and do not rule anything as impure except with certain conviction that you can swear upon; otherwise, the suffering will continue.
