What is the ruling on purifying electronic devices that have been touched by ritually impure hands, and can they be wiped with a damp cloth? And is it permissible to adopt the view of Imam Malik regarding the non-transfer of impurity from a dry impure object to a wet pure object, to avoid hardship?

You are afflicted with Waswasah (obsessive doubts), and its cure is to ignore it. We have explained the cases of impurity transfer, and that there is no harm in adopting the view of the Malikis during hardship. With doubt about the transfer of impurity, it is not ruled that it has transferred. The original state is purity, and one does not deviate from it except with certainty.
