Grand Ayatollah Sayyid Khamenei (may God protect him):

In the matter of purity and impurity, the default ruling in the eyes of sacred law is purity. As long as there is no certainty of impurity, things are considered pure for us, even if we have a strong suspicion of impurity. There is no need to investigate or inquire.

Grand Ayatollah Sayyid Sistani (may God protect him):

Anything that one doubts its impurity, while knowing it was pure previously, is considered pure. This also applies if one is unaware of its previous state (whether it was impure before the doubt or pure). There is no need to investigate what one doubts regarding its purity or impurity, even if the investigation does not require much effort. However, if one doubts its purity after knowing it was previously impure, it is ruled as impure.
