Does urine transfer to the hair and headscarf if a hand contaminated with urine touches the head covered by the niqab and headscarf?

When in doubt about the transfer of impurity, the original state of purity remains, and the transfer of impurity is not ruled by mere doubt. So, if there is doubt about the impurity of the niqab, its original state is purity. And if it is certain that the niqab has been afflicted with impurity, but there is doubt about its transfer to what is beneath it, then the original state of what is beneath it is purity, and the impurity is not considered to have transferred to it.
