Are a baby's clothes or the tap considered impure if the mother touches them with a hand moistened by the baby's urine, and does this ruling extend to everything in the house?

The answer indicates that the questioner is afflicted with waswasa (obsessive whispering/doubts) and advises her to disregard it and pay no attention to it. It emphasizes that the default state of things is purity, and something is not judged to be impure merely based on doubt. Therefore, unless there is absolute certainty that the faucet has become impure, it should not be ruled as such. If it is certain that the faucet has become impure, then purifying it is easy: simply pour water over it until the impurity is removed. The answer mentions the scholarly disagreement regarding the transfer of impurity from an impure hand to the faucet, and then to wet objects that touched it. It recommends adopting the view of those who say that impurity does not transfer in this situation, in order to دفعًا للوسوسة (repel obsessive doubts) and رفعًا للحرج (remove hardship).
