What is the ruling on the dry spots that appeared on the tiles after a period, which resemble urine stains, and is the carpet that the husband stepped on with a semi-wet foot considered impure if these spots are impure, and what is the extent of its effect on the rest of the house?

"Disregard the whispers (waswas) and ignore the doubts. The best cure for whispers is to turn away from them. As long as you are not certain that urine has touched the tiles, the original ruling is that they are pure. Do not rule something impure except with absolute certainty, for the original principle is purity, and this certainty is not removed merely by doubt. The original principle is the purity of everything you doubt has become impure. So, do not pay attention to your whispers and delusions."
