If I accidently touch a cold can of beer in a store and the condensation of the can leaves water on my hand even though the can is unopened and the water is the water that accumulated on the outside of the can from the temperature of the fridge, do I have to wash my hands from this, or should I leave it alone as it is just condensation on the can given that it is an unopened can?

All perfect praise be to Allah, The Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.

This water is ruled to be pure as there are no grounds to rule that it is impure. Therefore, you are not obliged to wash your hands from this water that has accumulated on the outside of the can.

Allah knows best.
