What Happens If Istinja’ Water Enter the Urethra?
If someone causes water, oil or anything else to enter the urethra then it comes out, it is impure and invalidates Wudu. This applies if the water reaches the inside, in the sense that when it comes out it is regarded as coming out from the passage. But if it only reaches the opening of the penis, which is regarded as pure, and it does not go any deeper, then it has no impact.
