Are the places you visited considered pure in the event that the time of impurity's occurrence is not remembered, and it is a Waswas (whisper from Shaytan), and does the sun purify a very small amount of urine, taking into account Imam Abu Hanifa's view on that, and is it permissible for someone afflicted with Waswas to adopt the easiest of opinions?

"Obsessive whispering (waswasah) is one of the most evil ailments, and its cure is to ignore it. The basic principle regarding something is that it is pure when there is doubt about its contamination or the transfer of impurity from it. The earth and what is connected to it, such as trees and buildings, become pure by drying. It is permissible for someone afflicted with waswasah to adopt the easiest opinions to remove hardship, and a small amount of impurity is unconditionally excused."
