I have been suffering from a multitude of physical and mental health related issues for the last few months. Today whilst in the toilet I felt a bit of discharge which I looked up and found to be wadhi come out with the urine. I washed the whole area very thoroughly with a hand shower. But when I came out it felt very slippery. I want to know if I was still considered najis or since I washed it many times it became tahir?

As long as you perform the 9 khuratat ( 9 ways of cleaning yourself after urinating ) then anything you feel after that will not be considered najis
