What is the ruling on neglecting purity and the spread of impurity throughout the house without knowing its exact locations? Is its dryness sufficient to purify it? What is the ruling on clothes that are not clearly soiled with impurity? What is the ruling on another house where purity is not maintained, and in the case of dry urine on mattresses and sitting on them when wet?

Your previous questions and this one indicate that you are afflicted with waswasah (obsessive whispering), and we warn you against giving in to it. The basic principle is that things are pure unless their impurity is confirmed with certainty. The soiling of clothes is not proof of impurity. The ground becomes pure by drying, according to many scholars. Impurity does not transfer, according to some scholars, if one of the two objects is wet, with the condition explained in Fatwa no. 116652. There is no blame upon you for acting upon these facilitative opinions as long as you are afflicted with waswasah, and do not rule something impure except with absolute certainty.
