Please forgive me if this is a daft question.
Below is a link to slippers similar to that which I wear in the bathroom/toilet.
Before entering the shower, urine fell on them and hence I rinsed them out throughly and left them to dry whilst I showered.
After showering I put the slippers on the floor and wore them. The floor has urine drops on it. The floor became considerably wet because water fell from my hair and then from my feet as I rinsed them again in the sink and then wore my slippers. By the time I got dressed and exited the bathroom there was essentially a mini flood on the floor and therefore both the bottom of the slippers and where I place my feet were wet.
My concern is that there so much water on the floor that some of it, along with the urine drops, soaked through to my feet making them napaak and therefore when I walked in the carpeted room, with wet feet, the carpet became napaak for the purposes of Salah.
In such a situation, should I ignore this as a baseless doubt or is it a distinct possibility that what I have described above could have happened?
