Is the impurity that spread throughout the house due to walking with urine on the ceramic tiles after wiping them with dirt considered among the pardoned impurities, and have the rooms that the brothers trod upon with their wet feet become impure after they passed over the impure ceramic tiles?

We ask Allah to cure you of waswasah (obsessive whispering). Nothing is considered impure merely by doubt; the default state of things is purity, and a pure thing remains pure until you are certain of the transfer of impurity to it by seeing or smelling it. If feet are not washed with water, they are not purified by earth. The walking of impure feet on tiles does not mean the entire house becomes impure; the impurity may be consumed or dry up and not transfer if the feet become dry, and washing the tiles is sufficient.
