The front of my shoe was najis (due to urine that had fallen on it) and there was snow outside and I stepped in places where the snow was deep, now I don’t know if my shoe is pure or not.

1) If snow touched it once does it suffice? (small quantity of snow)

2) Or does it have to touch it twice?

3) If I don’t know if now my shoes or najis or not after having come into contact with snow do I treat them as pure (I don’t know if the quantity was enough or not or if it touched twice or not)

Nnow doesn't make things pak water has to run on it
